This plot shows the distribution of rotation periods for 15,000 minor planets as of September 2016, plotted against their diameters. Most bodies have a period between 2 and 20 hours. [1] [a] This is a list of fast rotators—"minor planets" (which includes asteroids) that have an exceptionally short rotation period, i
This list contains the fastest-rotating minor planets with a period of less than 100 seconds, or 0.0277 hours. Bodies with a highly uncertain period, having a quality of less than 2, are highlighted in dark-grey. The fastest rotating bodies are all unnumbered near-Earth objects (NEOs) with a diameter of less than 100 meters (see table).
This makes it the first extrasolar planet to have its rotation rate measured. [11] With a rotation period of 8.1 hours, it was the fastest-spinning exoplanet known as of 2014. [11] [12] [13] Its rotation period is faster than that of Jupiter, which has a rotation period of around 10 hours. The rotation period was later refined to 8.7 ± 0.8 ...
The pace could be caused by a flashing magnetic field rather than pulsar rotation alone. ... as the slowest one ever observed, rotating just once every 6.45 hours, and explain that scientists have ...
Astronomers have discovered a huge planet with the fastest wind speeds ever observed in the universe.. The gas giant WASP-127b, which is located over 500 light-years away from Earth, has winds ...
Title Planet Star Data Notes Most massive The most massive planet is difficult to define due to the blurry line between planets and brown dwarfs.If the borderline is defined as the deuterium fusion threshold (roughly 13 M J at solar metallicity [30] [b]), the most massive planets are those with true mass closest to that cutoff; if planets and brown dwarfs are differentiated based on formation ...
Most minor planets have rotation periods between 2 and 20 hours. [1] [3] As of 2019, a group of approximately 650 bodies, typically measuring 1–20 kilometers in diameter, have periods of more than 100 hours or 4 1 ⁄ 6 days. Among the slowest rotators, there are currently 15 bodies with a period longer than 1000 hours. [1]
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
