The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is suspected. [39] HD 101581 c: 0.0925 6.21 transit 41.7 0.740 ± 0.087 4675 ± 53 Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is ...
As of 2024, 2018 VG 18 is the second-most distant observed Solar System object from the Sun and is the first object discovered while beyond 100 astronomical units (AU), overtaking the dwarf planet Eris (96 AU) in observed distance.
Dwarf planet Eris, similar in size to its better-known cosmic cousin Pluto, has remained an enigma since being discovered in 2005 lurking in the solar system's far reaches. While Pluto was ...
The planet KMT-2020-BLG-0414Lb is close in mass to Earth and is one of the least massive exoplanets detected by microlensing. [2] It is about twice as far from its star as Earth is from the Sun. The second companion, KMT-2020-BLG-0414Lc, is a brown dwarf about 30 times the mass of Jupiter .
It is around a newly discovered dwarf planet, named Quaoar. Home & Garden. Lighter Side
Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an "ocean world" with a big reservoir of salty water under its frigid surface, scientists said in findings that raise ...
2014 UZ 224 is a trans-Neptunian object and possible dwarf planet orbiting in the scattered disc of the outermost Solar System. As of 2021, it is approximately 89.7 AU (13.42 billion km) from the Sun, and will slowly decrease in distance until it reaches its perihelion of 38 AU in 2142.
