List of the largest known stars in the Milky Way Star name Solar radius (R ☉) Method [a] Notes Orbit of Saturn: 2,047 – 2,049.9 [10] [b] Reported for reference: Theoretical limit of star size (Milky Way) ≳1,700 [11] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of supernova ...
This list only concerns "living" stars – those which are still seen by Earth-based observers existing as active stars: Still engaged in interior nuclear fusion that generates heat and light. That is, the light now arriving at the Earth as images of the stars listed still shows them to internally generate new energy as of the time (in the ...
Located at a distance of 17,090 light-years (5,240 parsecs), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. [10] It is estimated to contain approximately 10 million stars, with a total mass of 4 million solar masses , [ 11 ] making it the most massive known globular cluster in the Milky Way.
Omega Centauri, one of the largest star clusters. Below is a list of the largest known star clusters, ordered by diameter in light years, above the size of 50 light years in diameter. This list includes globular clusters, open clusters, super star clusters, and other types.
The former head of the United Automobile Workers (UAW) union was one of the biggest contributors to the original Earth Day, donating $2,000 in 1970 (the equivalent of more than $15,500 today).
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars in other arms of the galaxy, which are so far away that they cannot be individually distinguished by the naked eye.
The newly-discovered binary star system, which is home to two stars gravitationally bound to one another, was found in a dense stellar cluster orbiting Sagittarius A*, which has an estimated mass ...
