what is the 2nd smallest planet in our solar system？
Closest to the sun, Mercury is the second smallest planet in our solar system. It has an orbital period of 87.97 Earth days and rotates on its axis once every 59 Earth days.
Furthermore,What are the 2 smallest planets?
Pluto used to be the smallest planet, but it's not a planet any more. That makes Mercury the smallest planet in the Solar System. The second smallest planet in the Solar System is Mars, measuring 6792 km across.
Likewise,What are the 3 smallest planets?
Though Mercury, Venus, Earth, and Mars are the smallest of the known planets, each is clearly impressive in different ways.
In this regard,Is Jupiter the second smallest planet?
The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter's mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth's diameter.
Similarly,What are the planet sizes in order?
For example, if you order the planets by size (radius) from biggest to smallest, then the list would be:
- Jupiter (43,441 miles/69,911 kilometers)
- Saturn (36,184 miles/58,232 km)
- Uranus (15,759 miles (25,362 km)
- Neptune (15,299 miles/24,622 km)
- Earth (3,959 miles/6,371 km)
- Venus (3,761 miles/6,052 km)
VenusThe second planet in the solar system, Venus, is the third smallest planet with a radius of 3761 miles (6052 km).
Saturn has 82 moons. Fifty-three moons are confirmed and named and another 29 moons are awaiting confirmation of discovery and official naming. Saturn's moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena.
If we put our planets in 'size order' they would be listed as the following, from large to small: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Since we lost Pluto as an official planet, it appears that Mercury is now considered the smallest planet in the solar system.
VenusMean Temperatures on Each Planet Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system's hottest planet.
SaturnSaturn is the sixth planet from the Sun and the second-largest planet in our solar system.
Mercury is the smallest planet in our solar system – only slightly larger than Earth's Moon.
Mars, the fourth planet from the sun, is the second smallest planet in the solar system; only Mercury is smaller. Mars is about half (53 percent) the size of Earth, but because Mars is a desert planet, it has the same amount of dry land as Earth.
Pluto is now classified as a dwarf planet because, while it is large enough to have become spherical, it is not big enough to exert its orbital dominance and clear the neighborhood surrounding its orbit.
