According to radiometric dating and other evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in 365.256 solar days, a period known as an Earth sidereal year.

2020年9月29日 · The Sun has a radius of 696.340 km / 432.685 mi and a diameter of 1.39 million km / 864.000 mi. Earth, for comparison, has a radius of only 2.439 km / 1.516 mi, and a diameter of just 12.742 km / 7.917 mi. All the planets in our Solar System combined account for just 0.2% of the Sun’s mass.

2022年2月14日 · To fully understand the scale of our sun, let’s compare its size to each planet of our solar system. Mercury: The Sun is 277 times larger than Mercury. 21 million Mercury-sized planets could fit inside the Sun. Venus: The Sun is 115 times larger than Venus. 1.5 million Venus-sized planets could fit inside the Sun.

2024年4月27日 · These comparisons highlight the Earth's relatively small size in the context of our solar system. Despite providing a home to all known life forms, the Earth is a tiny oasis amidst the vast expanse of space. The Sun's mass is about 1.989 x 10^30 kilograms, while Earth's mass measures around 5.97 x 10^24 kilograms.

2016年6月18日 · The Sun is a star at the center of the solar system. It represents almost a perfect sphere made up of hot plasma and magnetic fields. Its diameter is about 1 392 000 km, nearly 109 times larger than the Earth, and its mass (1.9891 × 1030 kg – 330,000 times the Earth) makes up about 99.86% of the total mass of the solar system.

2022年6月10日 · What is the size of the sun compared to the earth? – At about 864,000 miles (1.4 million kilometers) wide, the sun is 109 times wider than Earth, and it accounts for more than 99.8 percent of the solar system’s.

2022年7月15日 · How Big is the Sun Compared to the Earth? Sun to Earth Size Comparison – To put it simply, the Sun is as big as more than 1 million Earth masses put together. It is 1,287,000 times bigger than a solitary Earth. The Sun has a diameter of 1,392,000 km (865,000 miles) while the Earth’s diameter is only 12,742 km (7,918 miles).

Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation.

Compared to Earth, the Sun is enormous! It contains 99.86% of all of the mass of the entire Solar System. The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth. It is so large that about 1,300,000 planet Earths can fit inside of it.

Earth is small compared to the Sun, in the volume of the Sun could put more than a million Earths (1,305,620). Its average diameter is ≈ 12 742 km and that of the Sun, ≈ 1,392,684 km (≈ 109 times larger). The image shows the size ratio Earth / Sun, if the Earth stood on the same plane, very close to the Sun.
