The Sun is the center of our Solar System, a massive celestial body composed primarily of hydrogen and helium. Its immense gravity holds all the planets, including the Earth, in orbit around it. Emitting light and heat due to nuclear fusion, the Sun plays a crucial role in sustaining life...
It is investigated footprints of the effective gravity in the solar system. The inertial anti-gravitational potential of the sun allows to explain the anomalous acceleration of Pioneer 10 and 11, the anomalous increase in the lunar semi-major axis, the residuals of the seasonal variation of the ...
There are eightbig planets and five small dwarf planets in the solarsystem.Each planet orbits the sun. The strong pull of the sun'sgravity holds the planets orbit, which keeps them fromfloating away. Gravity is the same force that makes abaseball fall to the ground when you drop it.词汇...

In many ways, Mars can be considered Earth’s brother. On Mar’s surface, we have discovered the biggest mountain in the Solar System. It is named Olympus Mons, and it is three times bigger than the largest mountain on Earth. A day on Mars is also a little longer than a day on ...
The Sun is the star at the centre of our solar system. It is an almost perfect sphere of super-hot gases whose gravity holds the solar system together. The energy produced by the Sun is essential for life on Earth and is a driving force behind the Earth’s weather. ...
