Prominences are held above the Sun’s surface by strong magnetic fields and can last for many months.Prominences can loop hundreds of thousands of miles into space.An arc of gas that erupts from the surface of the Sun is called solar prominence.As solar flares are pushed through the corona, they heat its gas to anywhere from 10 to 20 million ☌.They are magnetic storms which appear to be very bright spots with a gaseous surface eruption.Solar flares are produced on the sun’s surface due to magnetic anomalies.Venus, the nearest and most similar planet to Earth in the Solar System, has an atmosphere 100 times denser than our own, with little or no geomagnetic field.Moreover, planets with a weak or non-existent magnetosphere are subject to atmospheric stripping by the solar wind.The solar wind is responsible for the overall shape of Earth’s magnetosphere.
Stars like Sun are rare in Milky Way galaxy, whereas substantially dimmer and cooler stars, known as red dwarfs, are common.Sun is equivalent to 3,32,900 Earth masses.
Comparatively, earth’s rotational velocity is 1675Km/hrs. Comparatively, the surface gravity of the earth and moon are 9.8 m/s 2 and 1.62 m/s 2 respectively.The surface gravity of the Sun is 274 m/s 2 (28 times the gravity of the Earth).In comparison, earth is about 5.5 times denser than water. That implies Iron is = 7.87 times denser than water. Temperature: 6000 ☌ on surface and 16 million ☌ in core.ĭensity of water = 999.97 kg/m³ = ~ 1 g/cm 3.Our solar system consists of the sun, eight major planets, dwarf planets (Pluto, Ceres, Eris etc.), satellites and countless minor planets, asteroids, meteors, comets and debris.
