Nemesis is a hypothetical red dwarf [1] or brown dwarf, [2] originally postulated in 1984 [3] to be orbiting the Sun at a distance of about 95,000 AU (1.5 light-years), [2] somewhat beyond the Oort cloud, to explain a perceived cycle of mass extinctions in the geological record, which seem to occur more often at intervals of 26 million years.
The second Death Star appears in Return of the Jedi, and a similar superweapon, Starkiller Base, appears in The Force Awakens. Both the original and second Death Star were moon-sized and designed for massive power-projection capabilities, capable of destroying an entire planet with a 6.2×10 32 J/s power output blast from their superlasers.

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.
Saturn's moon Mimas is known for its uncanny resemblance to the dreaded Death Star in the original "Star Wars" movie. ... it is the most unlikely place in the solar system to look for liquid water ...
When seen from certain angles, Mimas resembles the Death Star, a fictional space station and superweapon known from the 1977 film Star Wars. Herschel resembles the concave disc of the Death Star's "superlaser". This is a coincidence, as the film was made nearly three years before Mimas was resolved well enough to see the crater.
Despite being so small, Mimas boasts the second largest impact crater of any moon in the solar system — the reason it's compared to the fictional Death Star space station in “Star Wars.”
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
Mimas is the ‘most unlikely place in the solar system to look for liquid water’, ... Mimas is often compared to the Death Star from the Star Wars franchise because of its large Herschel Crater ...
