# Which star is located next to the moon?

The sun is the closest star to the moon. The moon revolves around the earth at about 238,857 miles - about 30 Earth diameters. The Earth's distance from the sun though is over roughly 93,000,000 miles - about 389 times the distance from the Earth to the Moon. Other planets orbit the sun as well. Here is a chart with some differences. http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/3-orbital-lengths-distances.html Note that Neptune is 4,913,500,000 miles - almost 53 times the distance from the Earth to the sun - 1590 times the distance from Earth to the moon. Driving non-stop at 60 miles per hour 24 hours a day 365 days a year it would take you roughly 9348 years to get to Neptune! And that's just IN our solar system. The next closest star is Proxima Centauri at 4.2 LIGHT YEARS away. A light year is VERY far. The distance light travels in a whole year. It takes just over 8 minutes for light to get from the sun to the Earth. So imagine how far it would go in an hour. Or a whole day. Now a year. OK. Now 4.2 years - that's how unbelievably far away the closest star is. 1 light-year = 63240 times the distance from the Earth to the sun (AU or astronomical unit). Every other star you see is even further away. Some are so far away you can't even write it using regular math - you need to use exponents. Needless to say, the moon moves along the sky in a totally different way than the stars do. So the moon has different stars that appear to be next to it constantly. at 10pm on May 1 a certain star may appear to be close but by midnight the moon has moved in relation to the star. On June 1 it may not even be close anymore or it may be close later in the evening. The stars rotate from the turning of the Earth. The Earth also rotates around the sun (a complete rotation is a year) so this is why the sky changes from season to season and Orion can be seen in winter and not in summer. Also, the sun revolves around the center of the Milky Way galaxy. It also runs up and down through the plan draggingt he Earth and all the other planets and moons along with it. And the Milky Way of course is screaming along outward towards the edge of the known universe. Some of the stars in the sky are in fact other galaxies so they move differently than the stars in our own galaxy. (but so slow we can't tell by just looking because of the vast differences involved). The universe is big. Very big. Nothing in space is "next to" anything. It can seem like it - much like a tree can look like it is next to the moon when it is on the horizon. But the distances in space are just absurd and you should try to avoid thinking of things as being close to each other.
