In Depth | Asteroids – NASA Solar System Exploration
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.
Asteroids, Comets & Meteors - NASA Solar System Exploration
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.
In Depth | Oumuamua – NASA Solar System Exploration
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.

In Depth | Perseids – NASA Solar System Exploration
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
Make Your Own Awesome Asteroid - NASA Solar System Exploration
Scientists predicted the existence of rubble pile asteroids that barely hold together in space. They are thought to be old fragments of asteroids that gently collided with each other to make a larger asteroid (process is called accretion).
