In 2006, Pluto was famously demoted from a planet to a dwarf planet. It remains the most famous dwarf planet today, but there are others in our solar system, including potentially hundreds that ...
In 2020, astronomers detected WD 1856+534 b, a gas giant that orbits a star 81 light-years from Earth. This exoplanet, which is roughly six times the mass of Jupiter (making it a "super-Jupiter"), was ...
In a groundbreaking discovery, astronomers have identified a potential dwarf planet candidate, 2017 OF201, buried within ...
The discovery of the Kuiper Belt revealed thousands of icy objects near Pluto, challenging its status as a planet. After the discovery of Eris, astronomers formally redefined “planet” in 2006, leading ...
Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic exoplanet system TOI-201. They include a super-Earth (TOI-201 d), a warm Jupiter ...
