What are the planets that revolve around the sun?

Eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Dwarf planets: Pluto, Ka Rong, Erin, Ceres, Birds and Pregnancy.

Asteroids: including Venus, Vesta, Venus, Venus and more than 500,000 unknown asteroids.

Planets revolve around the sun, and the sun, as a star of the Milky Way, also revolves around the center of the Milky Way. The revolutionary period has lasted about 250 million years. In other words, the sun moves around the center of the Milky Way with eight planets, such as the earth, which is a bit like being married and having children.

In this way, from space, the orbit of the earth's revolution is not a plane orbit, but a three-dimensional, that is, a spiral in the figure. In fact, not only does the sun move around the center of the Milky Way, but even the Milky Way is not static in the universe. It orbits a larger celestial body.

Einstein's general theory of relativity holds that

Gravity is the manifestation of space-time bending. The so-called space-time bending means that any object with mass will have an impact on space-time, and this impact is to distort space-time.

Small objects have little influence on time and space, so it is difficult to see. For example, an ant and a drop of water will have an impact on time and space, but it is difficult to measure.

The influence of massive celestial bodies on time and space is obvious, such as the sun, which can bend all the light passing near it, while black holes can lock the light and prevent it from escaping.

A massive celestial body will form a space-time depression or vortex around it. Any small-mass celestial body close to it will fall into its curved space-time depression or vortex, thus forming the phenomenon of being attracted to the past, which is the root of gravity.
