β¨A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circleβ¨

β¨The distinction between dwarf planets, asteroids, meteoroids and comets: simplistically, asteroids are relatively small inactive bodies composed of rock or metals; dwarf planets are the largest asteroids; meteoroids are smaller particles of asteroids (called meteors or "shooting stars" when they burn up in the atmosphere, and meteorites if they manage to penetrate to the Earth's surface); comets are mainly composed of dirt and ices rather than solid rock or metal, and tend to have dust and gas tails when close to the Sunβ¨

β¨The real color of the sun is white. The reason that the Sun looks yellow to us is because the Earth's atmosphere scatters higher wavelength colors, like red, orange and yellow less easily. Hence, these wavelengths are what we see, which is why the Sun appears yellowβ¨

What is the largest structure in the universe??
β¨The largest known structure in the Universe is called the 'Hercules-Corona Borealis Great Wall', discovered in November 2013 by Istvan hortvan
π₯This object is a galactic filament, a vast group of galaxies bound together by gravity, Measuring approximately 10 billion light years in lengthβ¨
