Scientists calculate the weight of the sun and use it as a reference in other accounts.
While space explorations are being carried out, the numbers that exist in space are instantaneous, and the numbers used to express these dimensions are abundant with zero. These numbers are also difficult to express, as well as the difficulty of communicating.
Solar Mass, meaning the weight of the sun, is actually used by physicists as a unit of measure. The mass of the sun is 1.989 x 10 ^ 30 kilograms, ie 333,000 times heavier than the Earth. However, dry holes, galaxies, and planets participating in the universe are so large that the mass of the sun is taken as a reference in order to express them.
Thanks to Newton, the calculation of the weight of the sun is not as difficult as it is known to be. The mass of the Sun affects the gravitational force of the Earth, and also the distance between planets returning to the orbit and the speed of these planets. If the Sun's gravitational force and mass were a bit more, our Earth would be able to move on to the Sun.
With today's technology, astronauts make space exploration in a much simpler way, with technology helping to calculate their precision and precision numbers. When astronauts compare Newton's equations with the calculations they carry, they have almost discovered that all the calculations were accurate.
