How many Jupiter-like planets need to be combined to form a sun-like star? Is it possible to create such a star from a huge number of Earth-like planets? How many will be needed for this? The mass of the Sun is 2 * 10 ^ 30 kg, the mass of Jupiter is 2 * 10 ^ 27 kg, the mass of the Earth is 6 * 10 ^ 24 kg. Explain the answers.
Jupiter’s chemical composition is similar to that of the Sun. Therefore, for the formation of a star, you just need to collect the required mass, and then gravity will do everything by itself. This means that you need about N = (2 * 10 ^ 30 kg) / (2 * 10 ^ 27 kg) = 1000 planets similar to Jupiter to create a star similar to the Sun. It will not work directly to “collect” a star from planets similar to the Earth, since their chemical composition is very different.
