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

Feb 18, 2025 · Asteroids and comets that have orbits that can bring them into Earth’s neighborhood are called Near-Earth Objects (NEOs). They orbit within 30 million miles (48 million kilometers) of Earth’s orbit, or about one-third the distance between Earth and the Sun. The vast majority of NEOs are asteroids.

Feb 25, 2025 · 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.

1 day ago · The orbits of asteroids bring them within 120 million miles of the sun. Most near-Earth objects (NEOs) are asteroids that range in size from about 10 feet to almost 25 miles across.

Near-Earth objects are asteroids and comets with orbits that bring them to within 120 million miles (195 million kilometers) of the Sun, which means they can circulate through the Earth’s orbital neighborhood.

Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago. The current known asteroid count is: . Most of this ancient space rubble can be found orbiting our Sun between Mars and …

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).Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type (carbonaceous), M-type (), or S-type (silicaceous).

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.

Feb 26, 2025 · Asteroid, any of a host of small bodies, about 1,000 km (600 miles) or less in diameter, that orbit the Sun primarily between the orbits of Mars and Jupiter in a nearly flat ring called the asteroid belt. Hundreds of thousands of asteroids are known.
