- Next Five Asteroid Approaches - NASA Jet Propulsion ...About the Asteroid Watch Dashboard. 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. The object's name is displayed by hovering over its encounter date.
- Overview | Asteroids – NASA Solar System ExplorationAsteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt – a region between the orbits of Mars and Jupiter. Some asteroids go in front of and behind Jupiter.
- Asteroid Watch - NASA Jet Propulsion Laboratory (JPL)These objects are defined as asteroids that are more than about 460 feet (140 meters) in size with orbits that bring them as close as within 4.6 million miles (7.5 million kilometers) of Earth’s orbit around the Sun. CNEOS continuously monitors all known near-Earth objects to assess any impact risk they may pose.
- Killer Asteroid hitting Earth in 2022? Here is what NASA saysIn October 2022, a half-mile-wide asteroid called Didymos will approach Earth. The killer asteroid will be accompanied by its 500-foot-wide moon, which will be orbiting it. Given the huge size of Didymos and its moon, ground-based telescopes will be able to detect the asteroid very soon.
