Is a planet bigger than a star
WebA solar system is a star with its planets. Our solar system consists of the sun, the Earth and eight other planets. There are smaller objects in the solar system, like the comets, asteroids, and each planet's moons. A galaxy is a collection of stars (some of which have planets) which clump together, held to each other by their combined gravity. WebIf a planet gets too big (say, 20 times the mass of Jupiter) then its gravity is so strong that it collapses, nuclear fusion starts - and it becomes a small star. So there are no planets …

WebStars and Their Fates. In general, the larger a star, the shorter its life, although all but the most massive stars live for billions of years. When a star has fused all the hydrogen in its core, nuclear reactions cease. Deprived of the energy production needed to support it, the core begins to collapse into itself and becomes much hotter. WebBetween 0.073 solar masses (78 Jupiter-masses) and 13 Jupiter-masses, brown dwarfs do fuse their natural deuterium (heavy hydrogen, with an extra neutron) to helium. Below 13 Jupiters (0.0124 solar masses), fusion stops altogether. The brighter stars like our sun begin above 0.073 solar masses where they are hotter and emit more visible radiation.
Web27 okt. 2024 · There are planets that are known to orbit around neutron stars. The planet would be physically larger than the star, but much much less massive. An example is … WebBlue supergiant stars are typically larger than the Sun, but smaller than red supergiant stars, and fall into a mass range of between 10 and 100 solar masses. Typically, type-O and early type-B main sequence stars leave the main sequence in only a few million years, since they burn through their supply of hydrogen very quickly due to their high masses.
Web7 jul. 2016 · This link is a good primer on how atmospheric density relates to other planetary factors. In particular, you propose a planet that has less gravity than Earth and greater air density.. Given that less gravity will reduce air density, all else held equal, because the gas will be held less closely to the surface, you have to have a compensating factor: either … Web29 aug. 2024 · ” Planets cannot be larger than the sun, but they can be larger than certain types of stars.
