WebbThe results of many stellar size measurements over the years have shown that most nearby stars are roughly the size of the Sun, with typical diameters of a million kilometers or so. Faint stars, as we might have expected, are generally smaller than more luminous stars. However, there are some dramatic exceptions to this simple generalization.

Webb[12][13]It has a diameterof about 1,392,684 km,[5]about 109 times that of Earth, and its mass (about 2×1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System.[14] Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium.

WebbIf p = 1″ (one second of arc), the distance of the star is 206,265 times Earth’s distance from the Sun —namely, 3.26 light-years. This unit of distance is termed the parsec, defined as the distance of an object whose parallax equals one arc second. Therefore, one parsec equals 3.26 light-years. Since parallax is inversely proportional to ... Webb26 juni 2024 · However, because Proxima Centauri is a smaller and cooler red dwarf type star, the planet’s orbit is within the habitable zone. It’s thought that Proxima Centauri b receives approximately the same amount of solar energy as Earth does from our Sun. Here’s a full list of the 44 of the closest stars to Earth: Star Name.
