    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. Betelgeuse - Wikipedia

    en.wikipedia.org/wiki/Betelgeuse

    With an age of less than 10 million years, Betelgeuse has evolved rapidly because of its large mass, and is expected to end its evolution with a supernova explosion, most likely within 100,000 years. When Betelgeuse explodes, it will shine as bright as the half-Moon for more than three months; life on Earth will be unharmed.

    It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE). [7] However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium, [ 8 ] whereas Iapetus (r = 735 km) is the largest icy body that has been found to ...

    Comets may have been potential sources of water for early Earth, researchers said this week.. When Earth formed around 4.6 billion years ago, some water likely existed in that gas and dust ...

  6. Red supergiant - Wikipedia

    en.wikipedia.org/wiki/Red_supergiant

    In theoretical extreme mass loss models, sufficient hydrogen may be lost that helium becomes the most abundant element at the surface. When pre-red supergiant stars leave the main sequence, oxygen is more abundant than carbon at the surface, and nitrogen is less abundant than either, reflecting abundances from the formation of the star.

    An asteroid will briefly eclipse Betelgeuse, a bright star in the Orion constellation, causing it to disappear from view for those in a narrow strip of the globe.

  9. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    Marine debris and marine aerosols refer to particulates suspended in a liquid, usually water on the Earth's surface. Particulates in water are a kind of water pollution measured as total suspended solids, a water quality measurement listed as a conventional pollutant in the U.S. Clean Water Act, a water quality law.
