Some planets take the expression "you're your own worst enemy" to the extreme. At least, that's what astronomers found when ...

In the remote outer reaches of planetary systems, far beyond the orbit of known planets, enormous and mysterious worlds silently loop around their stars. Some drift as far as 10,000 times the ...

Ground-Based Photometric Detection of Extrasolar Planets Acta Astronautica46, 10-12. Hans-Jorg Deeg, J Ellen Blue, Laurance Doyle, V.P. Kozhevnikov, E.L. Martin, J. Schneider, 2000. A Search for ...

Two extrasolar planets, HD 209458b and TrES-1, are currently known to transit bright parent stars for which physical properties can be accurately determined. The two transiting planets have very ...

Some, called rogue planets, don't even orbit a star, but rather are floating through the cosmos untethered. An exoplanet known as K2-18b even achieved a degree of fame in April when a team of ...

Exoplanets are planets that orbit stars outside Earth's solar system. For that reason, these celestial bodies are sometimes also referred to as extrasolar planets. Advertisement Advertisement ...

Scientists have discovered a giant planet orbiting a tiny red dwarf star, something they believed wasn t even possible. The planet, TOI-6894b, is about the size of Saturn but orbits a star just a ...

The dwarf planet candidate’s closest point to the sun is about 7 billion kilometers, roughly 45 times that of Earth’s distance. One trip around the sun takes more than 24,000 years.

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

The planet also interests scientists because it is strangely cold. Most of the gas giants discovered outside our solar system so far have been what are known as "hot Jupiters," where temperatures ...
