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.
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
Hottest (irradiated hot Jupiter) KELT-9b: KELT-9: 4050 ± 180 K [1] (3777 °C) The candidate planet KOI-2093.03 is hotter, at 6,285 K. [37] Kepler-70b and Kepler-70c are often described as the hottest known exoplanets, both at >6800 K (assuming an albedo of 0.1 for both), [38] but their existence are highly doubtful. [39] [40] Hottest (self ...
According to the Los Angeles Almanac, 57.2 °C (135.0 °F) was the hottest temperature historically recorded among 20 Los Angeles County weather stations. However, a nearby UCLA weather station less than three miles away recorded nothing close to this extreme claim. The Los Angeles Almanac has since stated "we offer no grounds for challenging ...
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.
Particular speeds bound paths to exceed the size and lifetime of the universe, i.e. the particle's total path traveled (but not the distance from its place of origin) since the beginning of the universe is less than the size of the universe [further explanation needed] (see least-energy in orders of magnitude (energy))
The highest-redshift quasar known (as of August 2024) is UHZ1, with a redshift of approximately 10.1, [48] which corresponds to a comoving distance of approximately 31.7 billion light-years from Earth (these distances are much larger than the distance light could travel in the universe's 13.8-billion-year history because the universe is expanding).
The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
