  2. List of largest stars - Wikipedia

    en.wikipedia.org/wiki/List_of_largest_stars

    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 ...

  3. List of Solar System objects by size - Wikipedia

    These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.

  4. KW Sagittarii - Wikipedia

    en.wikipedia.org/wiki/KW_Sagittarii

    KW Sagittarii is a red supergiant star, located approximately 2,420 parsecs (7,900 light-years) away from the Sun in the direction of the constellation Sagittarius.It is one of the largest known stars, with a diameter about 1,000 times larger than the Sun.

  5. UY Scuti - Wikipedia

    en.wikipedia.org/wiki/UY_Scuti

    They determined that all three stars are over 1,000 times bigger than the Sun and over 100,000 times more luminous than the Sun. The stars' sizes were calculated using the Rosseland radius , the location at which the optical depth is 2 ⁄ 3 , [ 20 ] with distances adopted from earlier publications.

  6. List of most massive stars - Wikipedia

    en.wikipedia.org/wiki/List_of_most_massive_stars

    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.

  7. Stellar classification - Wikipedia

    en.wikipedia.org/wiki/Stellar_classification

    Of the main-sequence star types, stars more massive than 1.5 times that of the Sun (spectral types O, B, and A) age too quickly for advanced life to develop (using Earth as a guideline). On the other extreme, dwarfs of less than half the mass of the Sun (spectral type M) are likely to tidally lock planets within their habitable zone, along with ...

  8. Blue supergiant - Wikipedia

    en.wikipedia.org/wiki/Blue_supergiant

    They are larger than the Sun but smaller than a red supergiant, with surface temperatures of 10,000–50,000 K and luminosities from about 10,000 to a million times that of the Sun. They are most often an evolutionary phase between high-mass, hydrogen-fusing main-sequence stars and helium-fusing red supergiants, [ 4 ] [ 5 ] [ 6 ] although new ...

  9. Hypergiant - Wikipedia

    The Pistol Star (V4647 Sgr), near the center of the Milky Way, in the constellation of Sagittarius. The Pistol Star is over 25 times more massive than the Sun, and is about 1.7 million times more luminous. Considered a candidate LBV, but variability has not been confirmed. V4029 Sagittarii; V905 Scorpii [20] HD 6884, [21] (R40 in SMC)
