Near-Earth objects are asteroids and comets whose orbits bring them within about 50 million km of Earth’s orbit. A few thousand are large enough and pass close enough to be flagged as potentially hazardous — a label about proximity, not an imminent threat. Each object’s page shows where it is right now on its journey around the Sun, how far it is from Earth, and when it next passes by.
Several of these worlds have been visited up close: Bennu and Ryugu were sampled and returned to Earth, Didymos’s moonlet was deliberately struck to test planetary defence, and Eros was the first asteroid ever orbited and landed on. Browse the spacecraft that made those journeys.
Frequently asked questions
How are asteroids named?
A newly found asteroid first gets a provisional designation encoding its discovery date (for example 2024 YR4). Once its orbit is well enough determined it receives a permanent number, and only then may the discoverer propose a name, which is reviewed and approved by the International Astronomical Union. That is why most objects you see here carry a number, a provisional code, or both.
What is the difference between an asteroid, a comet and a meteor?
An asteroid is a rocky body orbiting the Sun; a comet is an icy body that grows a tail of gas and dust when it nears the Sun. Both can be near-Earth objects and appear in this directory. A meteor is different — it is the streak of light made when a small fragment burns up in the atmosphere; if a piece survives to the ground it is a meteorite. Meteors are events, not tracked orbiting objects, so they are not listed here.
What makes an object “near-Earth”?
A near-Earth object is an asteroid or comet whose orbit brings it within about 1.3 astronomical units of the Sun, meaning it can pass relatively close to Earth’s orbit (roughly within 50 million km). It does not mean the object is near Earth right now — most are millions of kilometres away.
What are Apollo, Aten and Amor asteroids?
These are orbit classes. Apollo and Aten asteroids cross Earth’s orbit (Apollos spend most of their time outside it, Atens inside). Amor asteroids approach Earth’s orbit from outside but do not cross it, and Atira asteroids stay entirely inside Earth’s orbit. The class of each object is shown in this directory.
Has an asteroid ever hit Earth?
Yes, throughout history. Small ones enter the atmosphere daily and burn up harmlessly. Larger events are rare: the 2013 Chelyabinsk airburst (~20 m) injured people from shattered glass, the 1908 Tunguska event (~50 m) flattened forest in Siberia, and the ~10 km impact 66 million years ago contributed to the dinosaurs’ extinction. Objects capable of regional damage are exactly what monitoring programmes track and project decades ahead.
How many near-Earth objects are there?
More than 38,000 near-Earth asteroids are catalogued and the number grows as sky surveys discover more, often several per night. Around 2,400 are classed as potentially hazardous based on their size and how close their orbits come to Earth’s.
