Scientists have proposed two experimental spacecraft that could reach one of the farthest known objects in the solar system ...

Scientists may have discovered a dwarf planet far beyond Neptune — an unearthing that may disprove a longstanding theory about the possibility of a giant ninth planet. The dwarf planet's existence ...

A dwarf planet is classified as a celestial body that orbits the sun that has enough mass and gravity to be mostly round, but unlike other planets, has not cleared its orbital path of asteroids ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

Our solar system is a pretty wild place, full of amazing stuff. From the giant Sun to the tiny rocks floating around, there’s ...

Earth has a newly-discovered neighbor in the solar system. But the heavenly body – possibly a dwarf planet à la Pluto – isn't a frequent visitor. Located beyond Neptune, its extreme orbit ...

Studies of 15 M-type stars have revealed new insights into the potential presence of exoplanets. A new study led by ...

How many Earth-like exoplanets orbit M dwarf stars (Red dwarf stars), which are smaller and cooler than our Sun? This is what ...

Computer simulations show that planets could be flung out of the inner solar system, supporting the possible existence of a ...

Over the last few years, the term "Goldilocks zone" has come to be widely used to describe the range of distances from a star ...

Scientists from Vilnius University (VU) Faculty of Physics, along with members from Poland and other countries, discovered a rare planet using a space-time phenomenon first predicted by Albert ...
