Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

"We might have finally found the cause of a mystery that's lasted over 40 years," said researcher Sandino Estrada-Dorado.

NASA has significantly lowered the risk of asteroid 2024 YR4 hitting Earth. Last week, the asteroid had a 3.1% probability of ...

NASA has all but ruled out asteroid 2024 YR4 as a danger to Earth, reducing its impact probability to just 0.004% in 2032. However, a small risk remains for the Moon. Scientists are seizing the moment ...

As new asteroids become detectable, scientists compute their orbits, which takes time and refinement based on new ...

Chances an asteroid may hit Earth in 2032 dropped to near zero, astronomers say. Here's what to know about 2024 YR4.

NASA also said there’s a 99.9983% chance the asteroid will safely pass Earth in seven years, which is like a 1 in 59,000 chance of a collision. The new data shows there’s a 1.7% chance the asteroid ...

NASA says Earth is in the clear from asteroid 2024 YR4, which previously had a small chance of impacting our planet in 2032.

There's still a lot to learn about the space rock. Designated 2024 YR4, the asteroid was first reported by the Minor Planet Center on Dec. 27. The MPC, part of the International Astronomical Union ...

Six planets are visible in the night sky right now. On Feb. 28, Mercury will add a seventh planet to the planetary parade. Venus, Mars and Jupiter are 'great naked-eye targets' for beginning ...

It's not too late to see the planet parade. Stargazers will be able to see four or five planets in the night sky with their naked eye this month. A rare seven-planet alignment will reportedly be ...
