ad7hms | Is a figure 8 solar system possible? | I was wondering if it is possible for a solar system to exist where there are two suns that are essentially identical and a decent distance from each other so that the planet(s) are able to pass between them at one point in their orbit.

mukff | First question to AskScience. How much of the universe can't we see due to the extreme distances? | My title refers more specifically to the light from distant objects traveling to us, not so much about the light itself dissipating.
I understand the basic premise of the limitation light from super far away galaxies/stars (anything farther away in light years than ~Earth's age mean we can't observe them).

1ebhbo | Could an object orbit the moon at a really low height? (Like 500 ft, assuming it doesn't run into mountains) | [This picture](_URL_0_) goi me thinking about it. The moon has no atmosphere, so there's no air resistance. So could an object, going fast enough, orbit the moon at a low height?
EDIT: If the mountains are in the way, hypothetically bulldoze the moon's surface flat. | askscience | http://www.reddit.com/r/askscience/comments/1ebhbo/could_an_object_orbit_the_moon_at_a_really_low/ | {
