The newly identified cluster of Kuiper Belt objects lies about 4 billion miles from the Sun, offering fresh clues about how ...

"Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways," Nicolls ...

Astronomers are closing in on one of the most tantalizing possibilities in planetary science, evidence that a previously ...

An illustration of the solar system and the planet's orbits around the sun When you're standing on Earth's surface, it's easy to forget that our planet is hurtling around the sun at more than 67,000 ...

A new study of the orbit of comets suggests that the plane of the ecliptic, where the Earth's orbit rests, may not be the only major alignment in the solar system. By tracking the point where ...

An artist's depiction of a hot Jupiter planet orbiting its star. Skewed planetary pathways around a star aren't so strange after all. But fresh research led by Yale University shows that even ...

There goes another old astronomers' tale about where planets can't form. Scientists used to have a hard time detecting alien worlds in open star clusters, leading some to wonder whether a mysterious ...

In young solar systems emerging around baby stars, some orbits are more popular than others, resulting in ‘planet pile-ups’ and ‘planet deserts’ Computer simulations have revealed a plausible ...

Although the term itself immediately conjures the sort of alchemy at the heart of the best sci-fi fantasy, celestial mechanics —- the numerical nuts and bolts of how planetary bodies move, orbit and ...

NASA’s Parker Solar Probe launched a year ago on a mission to touch the sun. Since that fiery early morning liftoff with the mission’s namesake, Eugene Parker, in attendance, the probe has made two ...

Computer simulations have revealed a plausible explanation for a phenomenon that has puzzled astronomers: Rather than occupying orbits at regular distances from a star, giant gas planets similar to ...
