A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...
Recent observations from NASA’s James Webb Space Telescope revealed compelling evidence of a giant planet candidate orbiting Alpha Centauri A, a star in the nearest stellar system to the Sun. Led by ...
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 ...

Astronomers have made the first measurement of spin-orbit alignment for a distant ‘super-Jupiter’ planet, demonstrating a technique that could enable breakthroughs in the quest to understand how ...
Astronomers have discovered more than 300 exoplanetary systems that have three or more known planets. Most of these planets are about the same size and spaced close together, earning them the moniker ...
In an adiabatic encounter, the planetary orbit would adjust gradually to the changing gravitational field. In an impulsive encounter, the planetary orbit would be disrupted very suddenly. To test how ...
Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...
