Earth has a new “mini-moon” after an asteroid has joined our orbit.. The object, known as 2024 PT5, has been chasing after us for years. Now, it has become close enough to be pulled in by our ...
The asteroids in the inner solar system are hard to see, but a specialized camera can spot them briefly each night. These rocks are NOT expected to intersect with us.
The following is a collection of lists of asteroids of the Solar System that are exceptional in some way, such as their size or orbit. 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 ...
Pallas (minor-planet designation: 2 Pallas) is the third-largest asteroid in the Solar System by volume and mass. It is the second asteroid to have been discovered, after Ceres, and is likely a remnant protoplanet.
A top view of asteroid group location in the inner solar system A map of planets and asteroid groups of the inner solar system. Distances from sun are to scale, object sizes are not. Various dynamical groups of asteroids have been discovered orbiting in the inner Solar System.
A new study suggests that atoms could be stable at atomic number 164, which could help explain recent measurements of the ultradense asteroid 33 Polyhymnia.
Below is an example list of near-Earth asteroids that nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2023. During 2022, over 1,000 asteroids passed within 10 LD (3.8 million km) of Earth. Rows highlighted grey indicate a planet or main-belt asteroid
The team made mock asteroids roughly 12.5 millimeters in diameter—about the size of a coffee bean—from silica and quartz, to mimic the average composition of asteroids found in our Solar ...
