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.

Stars that are at least sometimes visible to the unaided eye have their apparent magnitude (6.5 or brighter) highlighted in blue. The first list gives stars that are estimated to be 60 M ☉ or larger; the majority of which are shown. The second list includes some notable stars which are below 60 M ☉ for the purpose of comparison. The method ...
Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi). [1] The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris)
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.
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 ...
Those most similar to class M stars have strong ZrO absorption bands analogous to the TiO bands of class M stars, whereas those most similar to carbon stars have strong sodium D lines and weak C 2 bands. [120] Class S stars have excess amounts of zirconium and other elements produced by the s-process, and have more similar carbon and oxygen
Based on results from the Gaia telescope's second data release from April 2018, an estimated 694 stars will approach the Solar System to less than 5 parsecs in the next 15 million years. Of these, 26 have a good probability to come within 1.0 parsec (3.3 light-years) and another 7 within 0.5 parsecs (1.6 light-years). [ 3 ]
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
