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
List of hottest exoplanets. 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 comparison, the hottest planet in the Solar System is Venus, with a temperature of 737 K (464 °C; 867 °F).
R136a1 has a surface temperature of around 46,000 K (45,700 °C; 82,300 °F), eight times as hot as the Sun, and with peak radiation in the extreme ultraviolet. [ 4 ] R136a1 has a B–V index of about 0.03, which is a typical colour for an F-type star .
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. [1] For few years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading.
Blackbody temperature of a small emitting area at the poles. [94] Suggested to actually be a low-mass quark star. Hottest non-degenerate star with a planet NSVS 14256825 b: NSVS 14256825: 40 000 K [95] NN Serpentis is hotter, with a temperature of 57 000 K, [5] but the existence of its planets is disputed. [96] Hottest normal star with a planet ...
Main-sequence stars vary in surface temperature from approximately 2,000 to 50,000 K, whereas more-evolved stars can have temperatures above 100,000 K [citation needed]. Physically, the classes indicate the temperature of the star's atmosphere and are normally listed from hottest to coldest.
WR 102, of spectral classification WO2, is one of the very few known oxygen-sequence Wolf–Rayet stars, just four in the Milky Way galaxy and nine in external galaxies. It is also one of the hottest known, with a surface temperature estimated to be at 210,000 K. Modelling the atmosphere gives a luminosity around 95,500 L☉, [5] while ...
The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan. [8] The theoretical maximum possible ground surface temperature has been ...
