This is a list of hottest stars so far discovered (excluding degenerate stars), arranged by decreasing temperature. The stars with temperatures higher than 60,000 K are included. List
The first list shows a few of the known stars with an estimated luminosity of 1 million L ☉ or greater, including the stars in open cluster, OB association and H II region. The majority of stars thought to be more than 1 million L ☉ are shown, but the list is incomplete. The second list gives some notable stars for the purpose of comparison.
The "U–V" colour from the HST WFPC2 336 nm and 555 nm filters is −1.28, more indicative of an extremely hot star. [12] This variation of different colour indices relative to a blackbody is the result of interstellar dust causing reddening and extinction.
The stars R126 and R66 in the Large Magellanic Cloud have luminosities of 1 400 000 L ☉ and 320 000 L ☉ [96] and have dust discs but no planets have been detected yet. Lowest stellar luminosity (main-sequence star) TRAPPIST-1 planets TRAPPIST-1: 0.0005495 L ☉ [105] [66] Hottest star with a planet PSR B0943+10 b and c: PSR B0943+10: 3 100 ...
This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500 K (2,230 °C; 4,040 °F) for exoplanets irradiated by a nearby star and greater than 2,000 K (1,730 °C; 3,140 °F) for self-luminous exoplanets.
No, actually -- even NASA is calling this star the "loneliest" in the universe. "The unusual object, called CX330, was first detected as a source of X-ray light in 2009," according to a NASA news ...

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.
