Asteroid foams bottom. The new 3D seismic data reveals astonishing details about For the purposes of this article, "asteroid" refers to minor planets out to the orbit of Neptune, and includes the dwarf planet Ceres, the Jupiter trojans and the centaurs, but not trans-Neptunian objects (objects in the Kuiper belt, scattered disc or inner Oort cloud). 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). 6 billion years ago. Oct 20, 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. Research and education will focus on utilizing planetary science principles for conceiving, implementing and validating space technologies, from systems design and control solutions, to robots and sensor networks, to mobility and excavation on small bodies. 2 days ago · Explore the 3D world of Asteroids, Comets and NEOs. Oct 27, 2025 · A massive crater hidden beneath the Atlantic seafloor has been confirmed as the result of an asteroid strike from 66 million years ago. These are near-Earth asteroids with orbits entirely within Earth's orbit. May 5, 2025 · Asteroids, sometimes called minor planets, are rocky remnants left over from the formation of our solar system about 4. Hundreds of thousands of asteroids are known. . Oct 23, 2025 · A scientist spotted an asteroid hiding in the sun's glare that orbits the sun in just 128 days, making it the second fastest known asteroid in the solar system. Discover the rocky objects orbiting our sun with the latest asteroid news, features and articles. Apr 25, 2025 · Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4. For the most up to date count of asteroids in our solar system please visit NASA/JPL's Solar System Dynamics website. 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). For the purposes of this article, "asteroid" refers to minor planets out to the orbit of Neptune, and includes the dwarf planet Ceres, the Jupiter trojans and the centaurs, but not trans-Neptunian objects (objects in the Kuiper belt, scattered disc or inner Oort cloud). Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Oct 28, 2025 · Astronomers discover 2025 SC79, the solar system's second-fastest asteroid, hiding in the Sun's glare. Oct 25, 2025 · The asteroid’s size, as well as its fast orbit around the Sun, qualifies it as a “planet killer” asteroid, which Sheppard had been searching for. Oct 22, 2025 · A scientist at the Carnegie Institute for Science has discovered a new asteroid in our neighbourhood. Atiras are the least numerous group of near-Earth objects and 2025 SC79 is the 39th member. Its name is 2025 SC79 and it's the newest member of the Atira asteroid group. Learn why these 'twilight' asteroids are a top priority for planetary defence. jgh y7vxye 4aqz qjxw3 pxsm7jm kq5 dgr u7i nvyt mcf3d0
