Answer . The truth is, the other planets DO have atmospheres. Planets other than Earth have gases surrounding the planet just like we do here. However, the types and/or quantities of gases in the atmospheres of other planets are simply not capable of supporting life like Earth is for one reason or… another. Venus, for example, has an atmosphere extremely rich in greenhouse gases such as Carbon Dioxide. Because of this, Venus is a VERY hot planet from all the solar radiation that is constantly beaming onto the planet with no way to escape. . Venus is not hot though find out more on wikipedia (MORE)
Venus is roughly the same size as Earth. Venus is about the same size as Earth. That is why it's called Earth's sister.
Venus Venus is sometimes regarded as Earth's sister planet. In some ways they are very similar: . Venus is only slightly smaller than Earth (95% of Earth's diameter, 80% of Earth's mass). . Both have few craters indicating relatively young surfaces. . Their densities and chemical compositions …are similar. Because of these similarities, it was thought that below its dense clouds Venus might be very Earthlike and might even have life. But, unfortunately, more detailed study of Venus reveals that in many important ways it is radically different from Earth. It may be the least hospitable place for life in the solar system. Mars Although Venus has a close elemental similarity, Mars has the closest physical structure, as it has retained usable gaseous carbon dioxide and liquid water. However, just as Venus has an atmosphere that is too dense, Mars is conversely too small to provide suitable atmospheric density. Titan Saturn's largest moon has an atmosphere that is analogous to Earth's, but much colder. It has nitrogen, oxygen, and some water. However, the thick atmosphere is so cold that water is always solid ice. Methane is instead the compound that exists as a gas, liquid, or frozen solid. (MORE)
All the planets have atmospheres. Some only tenuous like Mercury and some are completely made of gas like Jupiter.
No. Of the eight planets in the solar system, seven haveatmospheres. The only planet without an atmosphere is Mercury.
Uranus. it might not just be Uranus because there are so many sizes of planets
Uranus is roughly the same size as Neptune because Uranus is 51 118 km in diameter and Neptune is 49 532 km in diamter. From Lex Luther
Venus is a little bit smaller than Earth. Mars is considerably smaller than Earth. There aren't any other planets that are close to Earth in either size or mass.
Mainly, the mass of a planet doesn't matter, considering manyplanets are made up of gas, and how in different situations,atmospheres can be destroyed (The Sun burnt off Mercury'sAtmosphere). However, in some cases, the planet can be in a goodsituation on the galaxic map, and have great conditions fo…r anatmosphere, such as Earth. In which case, the mass of an object canattract a smaller object, causing gravity. Therefore, the biggerthe mass of a planet when in right and specific conditions, themore atmosphere it can attract, if there is any floating by theplanet. If it is bigger it will have more gravitational influence andtherefore gather more gases. (MORE)
Because of their relative sizes and distances from the Earth the Moon and the Sun appear to be roughly the same size. This is why, when the moon passes in front of the Sun during a total solar eclipse, the Moon apparently almost completely covers the disk of the Sun.
it blocks the HARMFUL UV rays of the sun, destroys meteorites heading to earth last but not least it reduces temperature differences on earth
no, they are not because I know that 1000 earths can fit into Jupiter,93 into Saturn but 3 Mercurys into an earth.
Venus is nearly the same size as Earth. The next closest in size would be Mars, at 1/3 Earth's size. I would not call that "nearly", though.
The amount of gravitational pull helps determine the gases that can form an atmosphere around a large body in space. So the mass of an object also determines the density of these gases. Note that several factors come into effect for a large object to sustain their gases if present. For example, hott…er, lighter, and faster particles more easily slip out of a planet's gravitational grip into space than cooler, heavier, and slower particles. Hydrogen and Helium are two of the lightest molecular-weight molecules. If they build enough escape velocity they will be ejected into space. (MORE)
The only planet close to earth in size is Venus, which is only 5% smaller. The second closest is Mars, which is just over half the diameter of earth.
In our solar system, Venus is closest to Earth's size - justslightly smaller at 95% of Earth's radius.
No planet is exactly the size of Earth. Venus is close to Earth'ssize but slightly smaller.
No. Seven of the eight planets in our solar system haveatmospheres. Only Mercury does not.
Zimbabwe - 390,757 km 2 Japan - 377,930 km 2 Germany - 357,114 km 2
No not really all have a atmosphere of some kind, some not fit to live in.
It is because plants take in carbon dioxide and breathe out Oxygen whereas, man and animals breathe in oxygen and breathe out carbon dioxide. This cycle of life maintaines a roughly same percentage of O2 and CO2 in the atmosphere.
This comprises the following layers: troposphere stratosphere mesosphere thermosphere exosphere The boundaries between them are: Tropopause Stratopause mesopause thermopause The composition of the atmosphere is about 78% nitrogen, 21% oxygen, with small amounts of other g…ases, for example: argon, water vapor, and carbon dioxide.

If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface g…ravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general. (MORE)
None that are known. It is either bigger or smaller than every other known planet in our solar system.
What are two planets that are the same size but have widely different atmospheres and surface conditions?
If you are talking about in our own solar system, and not Exo-Planets, then Venus and Earth are of almost identical size and mass. The only thing is Venus has a toxic atmosphere and acid rain, with temperatures that would boil water. While Earth... Well, you know what Earth is like.
Not exactly. Venus is the closest to Earth in terms of size comparison, it is a little smaller.
yes, just like Venus, it is the hottest planet and its atmosphere is made up of purely carbon dioxide.
Earth is not the only planet with atmosphere, lets take Jupiter and you might of herd of the red spot well that's a hurricane and out of the red spot there is a very thick layer of cloud, and all planets have an atmosphere but not mercury or Pluto if you count it.
planet earth would be rocks, oil, nothing but pure dirt carbondioxide and that is not good for peoples health and we would alldie and never come back alive in this life time . [Carbon Dioxide is a gas so the planet would still have anatmosphere even if incapable of supporting much life - includingp…robably that which was the origin of petroleum!] (MORE)
None of the planets in the solar system has an atmosphere much like Earth's, so it's kind of difficult to answer that. Mars is probably the best candidate, though it's much thinner.
Nobody owns the Earth. One could say mankind owns the Earth, but this is not true. We share the Earth with many other creatures without which we could not survive. So no one owns the Earth, we are merely living on it's shell for a finite time. What we do with it in that time is up to us.
to allow breathing and expiration of those mixtures necessary for life of all denizens of that planet
Saturn has an atmosphere, but it is not at all like Earth's. Earth has an atmosphere made mostly of nitrogen and oxygen. Dryair, i.e. not including water vapor, is about 78% Nitrogen, about21% Oxygen, and about 1% Argon. The amount of water vapor in theair varies considerably from often near zero i…n desert areas tosometimes more than 5% in hot, humid areas. Saturn's upper atmosphere is mostly hydrogen and some helium with afair amount of ammonia clouds and a smattering of acetylene,methane, ethane, and phosphine. Lower levels of the atmosphere arestill mostly hydrogen, although the amount of helium increases abit. Clouds are mostly made up of ammonium hydrosulfide in themiddle atmosphere and H 2 O in the lower atmosphere.Saturn has cloud bands in its atmosphere, but they're pale orangeand faded. This orange color is because Saturn has more sulfur inits atmosphere compared to Earth (or, for that matter, than itsneighbor Jupiter). Exact compositions are a little tricky todetermine since only the outer part of thee atmosphere is readilyobservable. Scientists are still not even certain if Saturn has arocky core or not. Note that while helium is a small fraction of the gas (less than10%), since it has about 4 times the atomic weight of hydrogen, andtwice the molecular mass, it makes up about 25% of the MASS of theatmosphere of Saturn.

Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, with 0.93% Argon and 0.038% Carbon Dioxide. Around 1% of the atmosphere is water vapour, with traces of other gases such as Neon, Xenon and Carbon Monoxide.
Venus is close, at 12,104 km versus the Earth at 12,756. The next closest planet is Mars, at 6,787 km, but that is not very close, so the question is invalid.
Earth is not the only planet that has an atmosphere, it's just the only planet with an atmosphere that is capable of sustaining human life. Even the moon has an atmosphere! The gases in our atmosphere are uniquely combined in a way that is life sustaining, as opposed to mars, for example, which has …a very thin atmosphere lacking many of the gases we need to live.

Yes they do. They just may have different atmospheres. Earth has mostly nitrogen while Venus has mostly carbon dioxide.
\n \nNo planet! However, Venus has no moons and is not much smaller than Earth.
Venus is the same size as Earth and has no moonsand has a thick atmosphere of mostly carbon dioxide.
The atmosphere is made up of 71% nitrogen and 28% oxygen. The other 1% is mostly made up of the noble gas argon.
All of the planets in our solar system except Mercury, and severalof their moons, have atmospheres, but none is like Earth's atmosphere.
Earth is the only known planet to have significant amounts of free oxygen in its atmosphere. Also, it's the only planet in our solar system where nitrogen is the main gas in the atmosphere.
No. Many planets have atmospheres, but most are made of noxious gases, have to great an amount of pressure, or are to cold or hot to be habitable for humans.
There is no simple relationship, but the general tendency is thatmore massive planets have more gravitational attraction, and areable to maintain a denser atmosphere. The amount of atmosphere aplanet has may also depend on it closeness to the Sun / to theplanet's star, and to its evolutionary histor…y. (MORE)
The size of each planet is precisely equivalent to the size of the planet which it is.
Venus, it diameter is 7,521 miles (12,104 km) while earth diameter is 7,918 miles (12,742 km)
Simply by coincidence Earth and Venus accumulated close to the sameamount of material when they formed.

Correct. Earth's atmosphere was necessary for the development oflife and is essential for its continued existence.
