More than a 150 years ago, before Neptune was ever sighted in the night sky, French mathematician Urbain Le Verrier predicted the planet’s existence based on small deviations in the motion of Uranus.

Engineers have designed a compact, battery-powered radio probe that could help unlock the secrets of alien planets. The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would ...

A study using NASA’s TESS data finds that aging Sun-like stars lose close-orbit planets as they evolve, offering insight into the long-term fate of planetary systems ...

The Sun is an incandescent but benevolent dictator. For billions of years, it’s kept our star system well organized through the influence of its powerful gravity. All the planets revolve around it on ...

The first exoplanet ever discovered in 1995 was what we now call a "hot Jupiter," a planet as massive as Jupiter with an ...

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it — very, very carefully. This is ...

The term "perihelion" describes the point in an astronomical body's orbit where it is nearest to the sun. Derived from the ...

The International Astronomical Union defines a planet as a celestial body that orbits the sun, is massive enough that gravity has forced it into a spherical shape, and has cleared away other objects ...
