Here's a little experiment you can perform to help you see the dramatic difference between a star and planet.

The life cycles of stars are fascinating, and sometimes the line between stars and planets isn’t as clear as it […] ...

Brown dwarfs have masses between 14 and 75 that of Jupiter’s and they form in isolation or pairs like stars.

To most of us, the difference between a star and a planet is pretty clear. But officially it's surprisingly murky, thanks to a middle-ground celestial object known as a brown dwarf, which could be ...

The difference in rotation probably generates the star’s magnetic field. Astronomers would have expected the planet’s orbital axis to align with the star’s rotation axis.

But it’s not just looks. Rocky composition, general size, orbital behaviors—a lot of those qualities can be the same on both ...

This is the process by which planets gradually move closer to their star due to the gravitational pull from the star. This causes the planet to lose energy and spiral inward over time, often ...

The James Webb Space Telescope has revisited a star that swallowed a planet and found that instead of the star subsuming the planet, it was the planet that crashed into the star.

For the first time, scientists have caught a star in the act of swallowing a planet - not just a nibble or bite, but one big gulp. Experts say that Earth will likely suffer the same apocalyptic ...
