Why are Earth and Saturn stars? How many Earths are needed to equal one Moon?

The Moon is the natural satellite of the Earth, which is one of the eight planets in the solar system. Neither the Earth nor Saturn can emit light by itself. In the solar system, it is the Sun, a powerful star, that attracts other planets and interstellar dust to move with it. The movement between celestial bodies is particularly interesting.

Why are Earth and Saturn stars?

The Earth and Saturn are planets. According to the definition of stars, the properties of the Earth and Saturn are not consistent with those of stars, but are more suitable for planets. This is mainly because the mass of the Earth and Saturn is not high enough to cause nuclear fusion inside them to achieve self-luminescence.

The Earth and Saturn do not belong to the category of stars, but to the category of planets. The definition of a star is that it must have internal gravitational cohesion, which leads to nuclear fusion within itself, and finally converts energy to make itself glow. Obviously, the Earth and Saturn cannot emit light by themselves, so they are not stars.

In the solar system, it is the powerful star, the Sun, that attracts other planets and interstellar dust to move along with it, including the Earth and Saturn. Under the guidance of the star, the Sun, the Earth and Saturn constantly revolve and rotate, which also proves the fact that they are planets.

The smallest star discovered so far, J0523, is small in size, but its mass is enough for hydrogen to undergo nuclear fusion. The Earth is not large and does not meet the standard. Although Saturn is large in size, its mass is not enough for nuclear fission, so the Earth and Saturn are not stars.

How many Earths are equal to one Moon?

The Earth is bigger than the Moon. We can only say how many Moons are needed to equal one Earth. In terms of volume, 49 Moons are needed to equal one Earth. In terms of mass, 80 Moons are needed to equal one Earth. The volume of the Earth is 108.32 billion cubic kilometers.

The Earth is one of the eight planets in the solar system, the third planet from the Sun, and the only celestial body known to nurture and support life.

The moon is commonly known as the month or the moon. It was called Taiyin, Xuantu, Chanjuan, and Yupan in ancient times. It is a spherical celestial body that revolves around the earth.

The Moon is the Earth's natural satellite and the fifth largest satellite in the solar system, with an average radius of about 1,737.10 kilometers.

The only silicon-based organism on Earth

So far, no silicon-based life has been found on Earth. Silicon-based life can be relatively defined as life composed of biological molecules with silicon skeletons. The concept of silicon-based life was first proposed in the 19th century, but from a chemical point of view, the hope of the birth of silicon-based life is very slim.

Silicon is widely distributed in the universe and is located below carbon in the periodic table, in the same main group, so it has many basic properties similar to carbon.

Silicon-based life is "non-carbon-based life" with silicon as the core element, relative to carbon-based life. It mainly contains substances such as silicon and silicon compounds.

Silicon-based life is very popular in science fiction, and many descriptions by science fiction writers put forward many useful ideas about silicon-based life.
