2020年9月29日 · Earth and Solar System Size Comparison Earth vs Mercury. Mercury is the smallest terrestrial planet, and overall the smallest planet in our Solar System. It has a diameter of only 4.879 km / 3.032 mi and a radius of 2.439 km / 1.516 mi and only 0.055 Earth masses. Our Earth is three times bigger than Mercury.

2019年12月6日 · Distance, Size and Mass. Earth is the third planet from the Sun, at a distance of 1 AU or 147 million km / 91 million mi. It is situated in the goldilocks zone where temperatures are just right for liquid water to exist and for life to evolve. Depending upon their current orbital positions, either Venus or Mercury are the closest planets to Earth.

2020年9月29日 · 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. Earth, for example, is 330.000 …

2020年9月29日 · How does the Moon compare to Earth? Our Moon’s diameter is more than a quarter of Earth’s diameter, while its mass is 1/81 that of Earth’s. It basically weighs 80 times less than our Earth. The Moon’s radius is only 27% of our Earth’s radius. If our Earth were hollow, it would take around 50 Moons to fill it.

2019年9月25日 · For a comparison, Mercury’s size is about a third of Earth, and Earth has a density of 5.51 g/cm³. Mercury has a radius of 2.439 km or 1516 mi, and a diameter of 4.879 km or 3.032 mi. Mercury's axis has the smallest tilt of any of the Solar System's planets at about 1 ⁄ 30 degrees, while its orbital eccentricity is the largest of all known ...

2020年9月29日 · It has a mean radius of 69.911 km / 43.440 mi, and its mass is equivalent to 318 Earth masses. Jupiter has more than 11 times the diameter of Earth. Some scientists estimated that if Jupiter were more than 70 times more massive, it would have probably turned into a star rather than a planet.

2019年11月5日 · Earth is about 3,959 miles, while Jupiter measures in at 43,441 miles. Earth is 5.972 × 10^24 kg, while Jupiter is 1.898 × 10^27 kg. While Earth only has one moon, Jupiter has 16 confirmed moons. Jupiter also has four rings. With such a size different, it only makes sense that 1,300 Earths could fit inside of Jupiter. It would take 3.5 Earths ...

Then the model Earth would be about 1.3 cm in diameter (the size of a grape). The Moon would be about 30 cm (about a foot) from the Earth. The Sun would be 1.5 meters in diameter (about the height of a man) and 150 meters (about a city block) from the Earth.

Size and Comparison. Earth is the fifth largest planet in the Solar System. It has a diameter of 6.371 km / 3.958 mi. It is the largest terrestrial planet. In comparison, Mercury has about 38% of Earth’s diameter. As such, Earth is almost three times bigger. When it comes to Venus, it has about 94% of Earth’s diameter.

2019年9月26日 · The core’s mass is estimated to be about 0.55% Earth masses with a radius less than 20% of the whole of Uranus. The mantle comprises its bulk, with around 13.4 Earth masses. The upper atmosphere is relatively insubstantial, weighing about 0.5 Earth masses and expanding for the last 20% of Uranus’s radius.
