Whether an asteroid is spinning neatly on its axis or tumbling chaotically, and how fast it is doing so, has been shown to be dependent on how frequently it has experienced collisions. The findings, presented at the recent ...
The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet that never formed. When our solar system formed 4.6 billion years ago, the material in this region ...
An international study led by researchers at São Paulo State University (UNESP) in Brazil has identified a little-known but potentially significant threat: Asteroids that share Venus's orbit and may completely escape current ...
Asteroid 2024 YR4 caused quite a stir last year when it was discovered and originally calculated to have a 3% chance of hitting Earth. Since then models have been refined and while it no longer has a chance of hitting Earth, ...
With help from amateur astronomers, scientists tracked how an asteroid traveled from space, broke up in Earth's atmosphere and sent fiery fragments shooting to the ground, gathering new information about how these space rocks ...
When considering the unnamed major features of all the moons, asteroids, and comets in our solar system, there are still a lot of places out there that need proper names. That means the International Astronomical Union (IAU), ...
Everyone who has ever lived on Earth has been well-aware of the moon, but it turns out Earth also has some frequent temporary companions. These "quasi-moons" are small asteroids that enter into a kind of resonance with Earth's ...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have made the highest resolution image to date, revealing new insights into the unusual and mysterious architecture of the debris disk encircling Fomalhaut, ...
Earth is so far the only known planet on which life exists—with liquid water and a stable atmosphere. However, the conditions were not conducive to life when it formed. The gas-dust cloud from which all the planets in the ...
Asteroid Bennu—the target of NASA's OSIRIS-REx sample return mission, led by the University of Arizona—is a mixture of materials from throughout, and even beyond, our solar system. Over the past few billion years, its unique ...
