Hace 1 día · 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). The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars.
Hace 3 días · 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.
6 de may. de 2024 · Antares, red, semiregular variable star, with apparent visual magnitude about 1.1, the brightest star in the zodiacal constellation Scorpius and one of the largest known stars, having several hundred times the diameter of the Sun and 10,000 times the Sun’s luminosity. It has a fifth-magnitude blue.
3 de may. de 2024 · For instance, UY Scuti holds the record for the largest known star, with a radius roughly 1,700 times that of the Sun. This colossal size means it would span beyond the orbit of Jupiter if placed at the center of our Solar System.
19 de may. de 2024 · Milky Way Galaxy (sometimes simply called the Galaxy), large spiral system of about several hundred billion stars, one of which is the Sun. It takes its name from the Milky Way, the irregular luminous band of stars and gas clouds that stretches across the sky as seen from Earth.
Hace 4 días · star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. Of the tens of billions of trillions of stars composing the observable universe, only a very small percentage are visible to the naked eye. Many stars occur in pairs, multiple systems, or star clusters.
Hace 2 días · The Sun is close enough to the Earth to appear as a disk instead, and to provide daylight. Other than the Sun, the star with the largest apparent size is R Doradus, with an angular diameter of only 0.057 arcseconds.
