A few notable large stars with masses less than 60 M☉ are shown in the table below for the purpose of comparison, ending with the Sun, which is very close, but would otherwise be too small to be included in the list. At present, all the listed stars are naked-eye visible and relatively nearby. Star name. Location.
Largest extrasolar apparent size star R Doradus: 1997 0.057" This replaced Betelgeuse as the largest, Betelgeuse having been the first star other than the Sun to have its apparent size measured. Smallest apparent size star Thousands of neutron stars located on the other side of the galaxy, likely impossible to resolve.
Representative lifetimes of stars as a function of their masses The change in size with time of a Sun-like star Artist's depiction of the life cycle of a Sun-like star, starting as a main-sequence star at lower left then expanding through the subgiant and giant phases, until its outer envelope is expelled to form a planetary nebula at upper right Chart of stellar evolution
It was the smallest known star from 1948 to 1981. TRAPPIST-1: 82,925: Hosts a planetary system with at least seven rocky planets. LHS 2090: 83,500 Teegarden's Star: 83,500 Has two potentially habitable planets. VB 8: 84,450 SPECULOOS-3: 85,570 Second-smallest star known to host a transiting exoplanet after TRAPPIST-1
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level. [1]
The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang (13.799 ± 0.021 billion years ago) to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age . Times on this list are measured from ...
Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi ). [1] The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars. ( Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis ...
A red dwarf is the smallest kind of star on the main sequence. Red dwarfs are by far the most common type of fusing star in the Milky Way, at least in the neighborhood of the Sun. However, due to their low luminosity, individual red dwarfs cannot be easily observed. From Earth, not one star that fits the stricter definitions of a red dwarf is ...
