What is the closest pulsar to earth?
The closest known pulsar to Earth is "PSR J0108-1431". It lies in the direction of the constellation Cetus, at a distance of about 85 parsecs (or 280 light years).

A supernova leaves behind a tiny object termed a neutron star, which is far smaller than the Earth. It is the core of the star that exploded. The protons and electrons of its …atoms have been squashed together by the force of the supernova, and they form the atomic particles known as neutrons. A neutron star is unimaginably dense. It contains the mass of the Sun, but has that mass squeezed into a ball perhaps 20km (12 1/2 miles) across. Further, neutron stars are so small that they can spin very rapidly, many times per second or faster. When they spin they emit electromagnetic radiation which can appear as flashes from earth. If the magnetic pole of the neutron star is "pointed" [See related link - Pictorial of pulsar] towards Earth, they are called pulsars, as they "pulse" as they spin and can be detected. The flashes produced by the pulsars are detected as the electro magnetic radio waves caught up by the radio telescopes The most notable pulsar is PSR B1919+21 with a period of 1.3373 seconds. When it was first discovered it was dubbed "LGM 1" for little green men 1, as the astronomers believed that only extraterrestrial life could generate such a precise signal. See related links for more information. The Pulsar is a car model by Nissan, but this question is in the Category of Astronomy, and its answer reflects that.
"UFO Sightings". Oddly Strange but True....
Strictly speaking, the CLOSEST star to the Earth is our own Sun. The next closest after that is Proxima Centauri, a tiny red dwarf 4.2 light years away. Even though it is the …closest star to the Sun, it cannot be seen by the naked eye, because it is too dim! The sun. It's a medium-sized star. Technically the sun is the star closest to the Earth, but because we experience it so differently from the other stars, we do not normally think of it as such. The closest star to us aside from the sun is Proxima, a small star that is part of the Alpha Centauri star system. On average, Proxima is 4.22 light years away while the star system as a whole is 4.27 light years away. The Sun is technically the closest star to the Earth. Besides that though, the star Alpha Centauri is closest. It is approximately 4.37 light years away The star closest to earth is the sun, averaging 93 million miles over the course of one full year. After the sun, the next nearest star is Proxima Centauri, roughly 270 thousand times farther from us than the sun is.
A Pulsar or Neutron Star is the remnants of a collapsed Super Giant, created during a Super Nova. The neutrons are so densely packed that they warp the gravity around the dyin…g star so that any radiation (radio waves) emitted from it doesn't always shine at us. Due to this warping the star becomes more like a light house and we can only see the beam when it is pointing straight at us. This constant on of is like a pulse hence the name Pulsar.
Most people wouldn't know what a pulsar was, so probably no.
No. The earth is closest to the sun in the first few days of January , and farthest from the sun in July.
The first layer above the surface is the Troposphere. This is followed by the Stratosphere, Mesosphere, Thermosphere, and Exosphere
The moon is closer to the earth than is the sun.
In our solar system, Venus is closest to Earth's size - justslightly smaller at 95% of Earth's radius.
Sirius is a star, not a planet, and it is not the closest star to Earth or anywhere near being the closest (technically the closest star to Earth is the sun, and the next clos…est is Proxima Centauri).
Hardly any - they are very far away. However, a supernova (which would come before a neutron star) could have catastrophic effects on Earth, if it were to happen in our neighb…orhood (up to a few thousand light years!).
A Pulsar is a highly magnetized, rotating neutron star that emit a beam of electromagnetic radiation . This can only be seen if the "beam" is pointing towards Earth.
Earth is a planet, not a star; it can never be a pulsar. For an excellent description of what life might be like on the surface of a pulsar, read the boon "Dragon's Egg" by …Dr. Robert Forward.
Pulsars are neutron stars that are formed when a large star burns up its fuel and collapses on itself. The process happens when fuel is exhausted so that the star cannot produ…ce heat energy which causes it to expand. Gravity causes it to collapse and then when it is suddenly so compacted the heat becomes so intense that it suddenly blows up because of uncontrollable nuclear fusion. The compressed core remains (neutron stars) and it spins on its axis with a beam of radiation and light coming from it. When the light goes in your direction you see a flash so that is why it is called a pulsar. Do you think I am a nerd?
Sun is the closest star to our Earth ( about 92.9 million miles away ) and it has everything to do with the earth . Sun is the father of entire solar system. Without sun the…re is no light, no heat energy and up above the all life isn't possible . so bow to the master .
