The moon is a bonanza for scientists, Kring says, because it offers crucial insights for understanding the origins and evolution of Earth and other planets: how they formed from the accretion and differentiation of smaller bodies; how they were bombarded by impacts early in their histories; and even how some of them migrated in their orbits around the sun.

Astronomers have spotted a small, faint moon orbiting the dwarf planet Makemake.

Nobody has ever conclusively seen a moon orbiting a planet in another stellar system, partly because their small size and great distance makes them difficult to find with modern detection methods.

It envisions the great reshuffling as a brief, violent affair that not only put the outer planets where they are today but also created the Kuiper belt of small icy bodies beyond Neptune, gave the planets scores of oddly orbiting moons, and bombarded the solar system with a rain of asteroids and comets so fierce that it would have cooked all but the deepest subterranean life on early Earth.

The idea is to capture a small asteroid, bring it into orbit around the moon using SEP, and then send astronauts to explore it — a daring and politically contentious concept called the Asteroid Redirect Mission.

A sizeable moon in retrograde orbit will, once captured, have a strong tidal effect on the primary (Neptune in this case) in such a way as to make the moon's orbit become both smaller and more nearly perpendicular to the primary's equator.

Ideas abounded: using ion engines to ferry up the components of a moon base; beaming power to robotic rovers on the Martian moon Phobos; attaching high - power Hall effect thrusters to the International Space Station (ISS) and putting it on a Mars cycler orbit; preplacing chemical rocket boosters along an interplanetary trajectory in advance so astronauts could pick them up along the way; using exploration pods like those in 2001: A Space Odyssey rather than space suits; instead of sending astronauts to an asteroid, bringing a (very small) asteroid to astronauts at the space station.

Now, new research in the journal Nature Geoscience suggests that an ancient collision could have sent a ring of debris containing at least 100 small moons into orbit around the Red Planet, which eventually coalesced into Phobos and Deimos — Mars's two current moons.

This is similar to how Earth's own moon formed from a ring of smaller satellites orbiting the planet.

For the most part, these planets have several small moons, all orbiting in the same direction as the planet spins.

It's a solar eclipse, with the Moon blocking the Sun, but because the Moon is at apogee — the point in its orbit farthest from Earth — the Moon appears smaller in the sky, so it doesn't completely block the Sun.
