Explore the 3D world of Asteroids, Comets and NEOs. Learn about past and future missions, tracking and predicting orbits, and close approaches to Earth.

An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the inner Solar System or is co-orbital with Jupiter (Trojan asteroids).

2025年2月7日 · Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago. Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt.

2024年11月3日 · Asteroids, sometimes called minor planets, are rocky remnants left over from the formation of our solar system about 4.6 billion years ago. Most asteroids can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt.

2 天之前 · Asteroids are airless, rocky masses, left over from the formation of the solar system some 4.6 billion years ago. ... Asteroids known as "trojans" share orbits with planets in the solar system.

We are the official body that deals with astrometric observations and orbits of minor planets (asteroids) and comets.

How do asteroids orbit? Almost all of the asteroids in our solar system are orbiting in a broad band 19,400,000 miles wide between Jupiter and Mars. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade.

See thousands of asteroids and comets in real-time, see the next five close approaches to Earth, and explore past, present and future missions to asteroids and comets.

Asteroids, sometimes called minor planets, are small, rocky fragments left over from the formation of the solar system about 4.6 billion years ago. Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter.

This sky map is a dynamic visualization that displays the real-time positions of asteroids in the night sky. It allows you to interactively explore their locations as they move along their orbits. By adjusting the view, you can track asteroid positions relative to the stars and see how their arrangement changes over time.
