YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a ...

NASA’s OSIRIS-REx mission tracked Bennu’s orbit with exceptional accuracy, allowing scientists to examine for subtle deviations. This study provides insight into the unknown forces in the ...

In 2016, NASA launched the spacecraft OSIRIS-REx towards the near-earth asteroid Bennu. The spacecraft managed to make contact in 2020, collecting samples which returned in 2023. Those samples ...

Astronomers are also closely watching the asteroid Bennu (.5 kilometers ... observatories and NASA can make more measurements to determine the object’s precise orbit and whether it may threaten Earth.

As more data comes in to further refine the orbit, it’s likely that this will continue to shrink. But just two days ago, the odds had grown to 3.1 percent, setting a record for the highest ...

Rocket Lab launched a high-resolution Earth-imaging satellite toward low Earth orbit this evening (Feb. 18). An Electron vehicle carrying the first "Gen-3" satellite for the geospatial ...

A private spacecraft carrying NASA instruments to the surface of the moon in preparation for astronauts to return in the years ahead has reached lunar orbit about a month into its spaceflight.

Bennu’s potential collision with Earth is a remote but unsettling possibility, according to a new study. Bennu is about 500 metres wide—taller than the Empire State Building and as wide as ...

Their combined mass is similar to that of Saturn’s moon Mimas. All these particles orbit Saturn in Saturn’s equatorial plane. The particles do not emit visible light of their own but reflect ...

Now, they’re planning to turn the powerful eye of the James Webb Space Telescope in 2024 YR4’s direction with the hopes of pinning down the space rock’s size and orbit. The Asteroid ...
