Stray asteroids and asteroid fragments have slammed into Earth and the other planets in the past, playing a major role in altering the geological history of the planets and in the evolution of life on Earth.

Our solar system?s small bodies ? asteroids, comets, and meteors ? pack big surprises. These chunks of rock, ice, and metal are leftovers from the formation of our solar system 4.6 billion years ago.

Meteors come from leftover comet particles and bits from broken asteroids. When comets come around the Sun, they leave a dusty trail behind them. Every year Earth passes through these debris trails, which allows the bits to collide with our atmosphere and disintegrate to create fiery and colorful streaks in the sky. The Comet

Our solar system consists of our star, the Sun, and everything bound to it by gravity ? the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

The first known interstellar object to visit our solar system, 1I/2017 U1 ?Oumuamua, was discovered Oct. 19, 2017 by the University of Hawaii?s Pan-STARRS1 telescope, funded by NASA?s Near-Earth Object Observations (NEOO) Program, which finds and tracks asteroids and comets in Earth?s neighborhood.

Phobos and Deimos appear to be composed of C-type rock, similar to blackish carbonaceous chondrite asteroids. Observations by Mars Global Surveyor indicate that the surface of this small body has been pounded into powder by eons of meteoroid impacts, some of which started landslides that left dark trails marking the steep slopes of giant craters.

Scientists weren't sure if asteroids could hold moons in their orbits until the Galileo spacecraft flew past asteroid Ida in 1993. Images revealed a tiny moon, later named Dactyl.

The composition of the moons outside the orbit of Oberon remains unknown, but they are likely captured asteroids. Unique Aspects Here's a sampling of some of the unique aspects of the moons: Miranda, the innermost and smallest of the five major satellites, has a surface unlike any other moon that's been seen.
