MERCURY
Mercury is the first planet from the Sun and the smallest planet in the Solar System. It is a terrestrial planet with a heavily cratered surface due to the planet having no geological activity and an extremely tenuous atmosphere.
Orbital period: 88 days
Distance from Sun: 58 million km
Radius: 2,439.7 km
Mass: 3.285 × 10^23 kg (0.055 M⊕)
Length of day: 59d 0h 0m
Gravity: 3.7 m/s²
VENUS
Venus is the second planet from the Sun. It is a rocky planet with the densest atmosphere of all the rocky bodies in the Solar System, and the only one with a mass and size that is close to that of its orbital neighbour Earth.
Length of day: 243d 0h 0m
Orbital period: 225 days
Distance from Sun: 108.2 million km
Gravity: 8.87 m/s²
Radius: 6,051.8 km
Mass: 4.867 × 10^24 kg (0.815 M⊕)
EARTH
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being a water world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's surface.
Age: 4.543 billion years
Radius: 6,371 km
Mass: 5.972 × 10^24 kg
Distance from Sun: 149.6 million km
Surface area: 510.1 million km²
Population: 7.888 billion (2021)
MARS
Mars is the fourth planet and the furthest terrestrial planet from the Sun. The reddish color of its surface is due to finely grained iron(III) oxide dust in the soil, giving it the nickname "the Red Planet". Mars's radius is second smallest among the planets in the Solar System at 3,389.5 km.
Gravity: 3.71 m/s²
Orbital period: 687 days
Length of day: 1d 0h 37m
Radius: 3,389.5 km
Coordinates: RA 12h 31m 49s | Dec -2° 49′ 26″
JUPITER
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, and slightly less than one one-thousandth the mass of the Sun.
Orbital period: 12 years
Gravity: 24.79 m/s²
Length of day: 0d 9h 56m
Radius: 69,911 km
Mass: 1.898 × 10^27 kg (317.8 M⊕)
Distance from Sun: 778.5 million km
SATURN
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine-and-a-half times that of Earth. It has only one-eighth the average density of Earth, but is over 95 times more massive.
Orbital period: 29 years
Length of day: 0d 10h 34m
Gravity: 10.44 m/s²
Distance from Sun: 1.434 billion km
Radius: 58,232 km
Coordinates: RA 22h 17m 30s | Dec -12° 30′ 41″
URANUS
Uranus is the seventh planet from the Sun and is a gaseous cyan ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which in astronomy is called 'ice' or volatiles.
Orbital period: 84 years
Length of day: 0d 17h 14m
Discovered: March 13, 1781
Distance from Sun: 2.871 billion km
Gravity: 8.87 m/s²
NEPTUNE
Neptune is the eighth planet from the Sun and the farthest IAU-recognized planet in the Solar System. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, and slightly more massive than its near-twin Uranus.
Orbital period: 165 years
Radius: 24,622 km
Discovered: September 23, 1846
Distance from Sun: 4.495 billion km
Length of day: 0d 16h 6m
