What is the closest pulsar to earth?

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 neighborhood (up to a few thousand light years!).

Most people wouldn't know what a pulsar was, so probably no.

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.

Hmmm. It's difficult to know precisely what you mean by that question. Is the Sun the closest object to the Earth? No, the Moon is less than a quarter-million miles away, while the Sun is 400 times farther away (at 93 million miles, on average). Is today the day on which the Earth and the Sun are closest together? No, the Earth reaches "perihelion" (closest point of approach to the Sun) on January 4 each… Read More

The Sun

Technically speaking, the sun is the closest star to Earth. . The next closest known star to the Earth is Proxima Centauri, red dwarf starapproximately 4.2 light years from Earth ... only about 278,000 times as farfrom us as the Sun is. See the related link below for further information aboutProxima Centauri. . The next two closest known stars comprise the binary star system called AlphaCentauri. Alpha Centauri is 4.4 light years from Earth… Read More

The Sun is the closest star to the Earth, at a distance of 8.3 light-minutes (93,000,000 miles). Proxima Centauri is the 2nd closest star to us, at a distance of 4.2 light years.

the sun is closest to earth The Sun is the star closest to earth

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… Read More

The Sun. The next closest star is located around 4 light years away from us and is named Proxima Centurai.

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 closest is Proxima Centauri).

the Sun

No. The sun is the closest star. The next closest star is Proxima Centauri

Yep..

Neptune

The Sun of our solar system behind that is Proxima Centari at 4.2 light years away

Rigil Kent, although it's really a triple star, the third component, Proxima, is just a wee red dwarf while the other two are one a little bigger and the other a little smaller than the Sun.

The sun is the closest star to earth.

That would be the sun.

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.

Yes.

yep, it will be a bit hot if there was one any closer

No. The moon is not a star. The Sun is the closest star to Earth.

The moon is the nearest astronomical body to Earth, but it's not a star. The nearest star to Earth is the Sun.

The Sun we see everyday. Our Sun (aka Sol)

Because of their binary orbit - Alpha Centari A and Alpha Centauri B are the second and third closest stars to us. Alpha Centauri C (Proxima Centauri) is the closest star to us.

The Sun.

Saturn.

Those that are closest are the closest stars to earth. The champion closest star ... the closest of all of them ... is the sun. Coming in at a distant second place, the next closest star is 278 thousand times farther from earth than the sun is.

After the sun it's Proxima Centauri

1. The sun 2. Proxima Centauri 3. Alpha Centauri A 4. Alpha Centauri B 5. Barnard's Star

Alpha Centauri is actually a triple star system; at any given time, one of the stars in that system is the third closest to Earth.

The Sun, followed by Proxima Centauri.

Yes.

1.5 light years but since the sun's gravity travels 1.5 light years it is part of our solar system

The closest star to the Earth is the Sun. See related question.

The sun.

The Sun. Sometimes, it's phrased as a trick question, but our Sun is a star just like all the others, entirely average in size. Other than the Sun, the next-closest star is Proxima Centauri, which is a red dwarf 4.2 light years away from Earth. Even though it is closest, it's too dim to see without a good telescope.

The sun is always by far the closest, regardless of time of day. The next nearest star is Proxima centauri, over 4 lightyears away.

The Sun is the Earth's closest star. Without the Sun there would be no light and no heat and life would not be able to exist on Earth.

Yes, it is. That is why the sun shines the brightest and looks biggest, while the others look smaller and less bright.

The Moon is not a star. The Sun is a star, but the Moon is a "moon" or satellite of Earth. The closest star to the Moon is our Sun.

Proxima Centauri.

sun

It's called the Sun.

The closest star to earth is the one we call "the sun", about 93 million miles away. The next closest one is Proxima Centauri, about 25.9 million million miles away.

Alpha Centauri.

Proxima Centauri, a red dwarf star in the constellation of Centaurus, is the nearest known star to the Earth after the Sun. It is 4.2 Light Years away.

Van Maanen's at 14 light years

The Sun is the closest star to Earth. The next closest star is 4.2 light years away. It is a red dwarf called Proxima Centauri.
