The size of UY Scuti compared to Earth's orbit and the Sun (barely visible) UY Scuti is a dust-enshrouded bright red supergiant [ 16 ] and is classified as a semiregular variable with an approximate pulsation period of 740 days.
Theoretical limit of star size (Large Magellanic Cloud) ≳1,550 [11] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of stars. Assumes an effective temperature of 3,545 K. Reported for reference: HV 888 1,477 [108] –1,584 [109] Large Magellanic Cloud L/T eff: HD 269551 A 1,439 [110 ...
It is over 100,000 times less dense than Earth's atmosphere at sea level (1.2 kg/m 3). In 2012, the size was calculated more accurately to be somewhat lower, for example 1,420 R ☉, [3] which leaves larger sizes published and in-date for other galactic and extragalactic red supergiants (and hypergiants) such as Westerlund 1 W26 and WOH G64.
A hypergiant star and its proplyd proto-planetary disk compared to the size of the Solar System. ... V430 Scuti [25] V452 Scuti, LBV ... UY Scuti [47] V602 Carinae ...
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
English: Size comparison of evolved red supergiant star Stephenson 2-18, extreme red hypergiant star VY Canis Majoris and luminous red supergiant star UY Scuti. Bahasa Indonesia: Perbandingan ukuran bintang super raksasa merah berevolusi Stephenson 2-18, bintang hypergiant merah ekstrim VY Canis Majoris dan bintang super raksasa merah bercahaya ...
Evolution of the solar luminosity, radius and effective temperature compared to the present-day Sun. After Ribas (2009) [3] The uncrewed SOHO spacecraft was used to measure the radius of the Sun by timing transits of Mercury across the surface during 2003 and 2006. The result was a measured radius of 696,342 ± 65 kilometres (432,687 ± 40 miles).
Stephenson 2 DFK 1, also known as RSGC2-01 [a] or St2-18, is a red supergiant (RSG) or possible extreme red hypergiant [2] (RHG) star in the constellation of Scutum.It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a ...
