Warm Jupiters are rewriting the rules of planet formation - showing eccentric orbits that stay strangely aligned with their ...
Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are like grains of sand in a region the size of a football field. The time that planets take to ...
Astronomers have discovered an alien world that defies every planetary rule with its massive size, low density, and tilted ...

Astronomers Say a 15-Degree Tilt Could Reveal a New Planet — And It’s Not Planet Nine
A recent study introduces the idea of Planet Y, a theoretical world that could explain strange gravitational behavior beyond ...
Astronomers observe for the first time the actual motion of spirals in a protoplanetary disk, revealing gravitational ...
The apparent brightness of celestial objects, rather than their proximity, is the primary factor determining observability. Andromeda Galaxy, despite its vast distance, appears significantly brighter ...
Astronomers are proposing a new, more quantitative definition of what makes a planet. The new definition looks more directly at the object's mass — but it would still leave Pluto out of the running.
On August 24, 2006, our solar system lost a planet. It wasn't by cataclysmic destruction, but rather by the vote of the International Astronomical Union, which declared that Pluto, considered the ...
Researchers are discussing 2025 PN7, a small celestial body that's following a similar orbital path to our planet's without being gravitationally tied to Earth ...
It's not going to happen ... probably. Astronomers have almost found all the kilometer-sized asteroids. There’s a little under 1,000 of them—and none of them will strike Earth in the next 1,000 years.
Orbital resonances can change how gravity influences two bodies, causing them to speed up, slow down, stabilize on their orbital path and sometimes have their orbits disrupted. Think of pushing a ...
