Planet of solar system with astronomical signs of the planets

The so-called “Planet Nine,” as scientists are calling it, is about 10 times the mass of Earth and 5,000 times the mass of Pluto. Here’s the order of the planets, starting nearest the sun and working outward through the solar system: MercuryVenus, Earth, Mars,JupiterSaturnUranusNeptune — and Planet Nine


(minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered.


Mercury is the smallest planet in the Solar System and the one closest to the Sun, with an orbital period of about 88 Earth days, which is much faster than any other planets in the solar system.

Orbital period 87.969 1 d; 0.240 846 yr; 0.5 Month
Sidereal rotation period 58.646 d; 1407.5 h
Average orbital speed 47.362 km/s
Equatorial rotation velocity 10.892 km/h


Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has the longest rotation period of any planet in the Solar System and rotates in the opposite direction to most other planets. It has no natural satellite.

Radius 6,052 km
Distance from Sun 108.0 million km
Mass 4.867 x 10^24 kg (0.815 M⊕)
Length of day 116d 18h 0m
Surface area 460.2 million km2
Orbit Period 225 days


Earth is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System’s four terrestrial planets.

Surface pressure 101.325 kPa (at ‎Mean Sea Level)


Mean radius 6,371.0 km (3,958.8 mi)


Surface gravity ‎9.807 m/s2 (32.18 ft/s2); (‎1 g‎ram)
Mean density ‎ ‎5.514 g/cm3 (0.1992 lb/cu in)


Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war.

Gravity 3.711 m/s²
Radius 3,390 km
Distance from sun 227.9 million km
Mass 6.39 × 10^23 kg (0.107 M⊕)
Surface Area 144.8 million km²



Jupiter is the largest planet in the solar system. It is approximately 143,000 kilometers (about 89,000 miles) wide at its equator. Jupiter is so large that all of the solar system.


Saturn is the sixth planet from the Sun and the second largest. … Early observations of Saturn were complicated by the fact that the Earth passes through the plane of Saturn’s rings every few years as Saturn moves in its orbit. … Saturn’s rings remained unique in the known solar system .

Distance from Sun 1.429 billion km
Radius 58,232 km
Mass 5.683 × 10^26 kg (95.16 M⊕)
Orbit Period 29 years
Orbit Sun


Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.

Distance from Sun 2.877 billion km
Radius 25,362 km
Mass 8.681 x 10^25 kg (14.54 M⊕)


Neptune is the eighth and farthest known planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Among the giant planets in the Solar System, Neptune is the most dense.

Distance from Sun 4.498 billion km
Radius 24,622 km
Mass 1.024 × 10^26 kg (17.15 M⊕)
Orbit Period 165 years
