The most recent figure established in 2017 by Ryder Windham gives the second Death Star a radius of 200 kilometres (120 mi). [32] The second Death Star is featured on the cover of the book Star Wars: Aftermath (2015), which also features many flashbacks to the destruction of the second Death Star, as well as the events directly after its ...
Size comparison of Sirius B and Earth. Sirius B, also known as the Pup Star, is one of the most massive white dwarfs known. With a mass of 1.02 M ☉, it is almost double the 0.5–0.6 M ☉ average. This mass is packed into a volume roughly equal to the Earth's. [56]
It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup; [1] however, later studies revealed that icy satellites as large as Iapetus (1,470 kilometers in diameter) are not in hydrostatic equilibrium at this time, [2] and a 2019 assessment suggests that ...
In an event that sounds more like an episode of 'Star Wars' than one of reality, scientists have discovered evidence of a death star literally ripping a planet apart with its gravity ...
Mimas is often compared to the Death Star from the Star Wars franchise because of its large Herschel Crater, which resembles the hollowed-out shape of the fictional space station’s laser weapon.
A yellow hypergiant, one of the rarest types of stars. V838 Monocerotis: 464 [79] L/T eff: During the 2002 Red Nova, the star's radius may have increased up to 3,190 R ☉. [80] Pistol Star (V4647 Sagittarii) 420 [81] L/T eff: One of the most luminous stars known. La Superba (Y Canum Venaticorum) 344 [82] L/T eff: Mira (ο Ceti A) 332–402 [83] AD
With a mass only 93 times that of Jupiter (M J), or .09 M ☉, AB Doradus C, a companion to AB Doradus A, is the smallest known star undergoing nuclear fusion in its core. [12] For stars with similar metallicity to the Sun, the theoretical minimum mass the star can have, and still undergo fusion at the core, is estimated to be about 75 M J.
This is Mimas, the smallest of Saturn's major moons. Other than its giant impact crater, scientists thought Mimas was a rather boring piece of cold rock. Now, a new study says Mimas is much more ...
