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 7, 2025 · Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.

Jan 29, 2025 · Lee esta nota de prensa en español aquí.. Studies of rock and dust from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft have revealed molecules that, on our planet, are key to life, as well as a history of saltwater that could have served as the “broth” for …

6 days ago · Asteroid 2024 YR4 is a near-Earth asteroid, meaning it is an asteroid in an orbit that brings it into Earth’s region of the Solar System. 2024 YR4. Explore; ... YR4 will be ruled out as an impact hazard, as has happened with many other objects that have previously appeared on the NASA JPL asteroid risk list. It is also possible its impact ...

This interactive visualization uses data from JPL's Center for Near Earth Object Studies (CNEOS), which computes high-precision orbits for Near-Earth Objects (NEOs) in support of NASA’s Planetary Defense Coordination Office.

Jul 3, 2024 · Scientists at NASA’s Jet Propulsion Laboratory in Southern California recently tracked two asteroids as they flew by our planet. One turned out to have a little moon orbiting it, while the other had been discovered only 13 days before its closest approach to Earth.

4 days ago · The Asteroid Watch dashboard tracks asteroids and comets that will make relatively close approaches to Earth. The dashboard displays the date of closest approach, approximate object diameter, relative size and distance from Earth for each encounter.

Nov 3, 2024 · Asteroids range in size from Vesta – the largest asteroid at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth’s Moon.

6 days ago · NASA’s James Webb Space Telescope will also observe the asteroid in March 2025 to better assess the asteroid’s size. Currently the asteroid is estimated to be 130-300 feet across. As more observations of the asteroid’s orbit are obtained, its …
