Distance from earth to nearest non- solar star?

Answer 1

The nearest star outside our solar system is Proxima Centauri, at 4.2 light years. Light travels 186,000 miles per second, so 3600 seconds per hour times 24 hours per day times 365.25 days per year = 31557600 seconds per year.

Times 186,000 miles per second times 4.2 light years equals 24,652,797,120,000 miles. To the CLOSEST other star.

The bright star Vega is only 25 LY away, so that's about 146,742,840,000,000 miles. Rigel, the brightest of the "nearby" stars, is about 800 LY away, so that's about 4,695,770,880,000,000 miles. In words, that would be 4.6 QUADRILLION miles.

The brightest single star that we are aware of is S Doradus in the Large Magellanic Cloud, one of the "daughter" galaxies of our Milky Way. S Doradus is 169,000 LY away, so in miles this would be 991,981,598,400,000,000 miles away.

All of the other galaxies are farther away than that, but they are so far away that we generally cannot see individual stars at that distance.

Answer 2

Proxima Centauri is the closest star to our Sun. Unfrtunately, Proxima is a very dim star, so more attention has been paid to the slightly father away Alpha Centauri, a star very similar to our Sun. Alpha Centauri is also known as "Rigel Kentaurus", or "Rigel Kent".

Proxima is about 4.2 light years away, while Alpha is about 4.4 LY distant.

Answer 3

At the moment we think its Proxima Centauri. But if you are really interested in this question, and i doubt you are, you may be interested in reading about 'Nemesis' a theorised brown dwarf somewhere beyond the Oort Cloud that may have a deadly link to the Earth's Life Cyle.

Answer 4

The average distance from the Earth to the Sun (which is the closest star) is 93 million miles (150 million km). Keep in mind that this is just an average due to the fact that the Earth orbits around the sun elliptically. This means that it follows the path of an ellipse around the Sun, and not a perfect circle.

When the Earth is at its closest point to the Sun (called perihelion) it's only 91.14 million miles (147 million km) from the sun.

And when the Earth is at its furthest point from the Sun (called aphelion) it's 94.24 million miles (152 million km) from the Sun.

Answer 5

There is only one star in the Solar System and that is the Sun.

The next nearest star is 4.2 light years away - and that is not in our Solar System.

Some astronomers have suggested that the Sun might have a very dim brown or red dwarf companion, far out beyond Neptune's orbit. The name generally given to this hypothetical companion is "Nemesis". However, the evidence for this is tenuous at best, and it's far from certain that it actually exists.

Answer 6

The nearest star from the Sun is Proxima Centauri, which is 4.2 light years away.

One Light Year is the distance that light travels in one year. That's 9,460,730,472,581 KM or 5,878,625,371,567 miles. That;s 9.46 TRILLION KM or 5.88 trillion miles.

Answer 7

the nearest star outside our solar system is Proxima centauri.

Answer 8

The closest star to our Sun, is the star Proxima Centauri, at 4.2 light years away.

Answer 9

Proxima Centauri is 4.2 light-years away. It is a small red dwarf star that is not visible to the naked eye.
