Using the Solar System for comparison, the orbit of Mars is about 1.5 AU, Ceres in the asteroid belt 2.7 AU, Jupiter 5.5 AU —so, assuming Betelgeuse occupying the place of the Sun, its photosphere might extend beyond the Jovian orbit, not quite reaching Saturn at 9.5 AU.
The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris) Overview Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red ...
Orange to red stars with complex band spectra, such as Betelgeuse and Antares. This corresponds to the modern class M. Secchi class IV: In 1868, he discovered carbon stars, which he put into a distinct group: [48] Red stars with significant carbon bands and lines, corresponding to modern classes C and S. Secchi class V
Earlier observations found that, if placed at the center of our solar system, the massive star Betelgeuse would stretch out beyond the orbit of Jupiter. This new study finds its body would only ...
In late 2019 and early 2020, Betelgeuse blew its top. Literally. Around that time the famous bright star marking the right shoulder of Orion suddenly started dimming, dropping to about half its ...
Betelgeuse—the star and not the slimy, suit-wearing demon—is one of the most celebrated celestial objects in the night sky. Found in the constellation Orion, Betelgeuse is extremely bright ...
Closest neutron star discovered to date. [14] PSR B1620-26: 24 Pulsar: An exoplanet orbits PSR B1620-26 and its white dwarf companion (see below) in a circumbinary orbit. HD 49798: 1,600 White dwarf: One of the smallest white dwarf stars known. [15] ZTF J1901+1458: 1,809 Currently the most massive white dwarf known. [16] Janus: 3,400
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.
