(Five major moons were discovered using Earth-based telescopes.)
The Solar System is orbiting the centre of the Galaxy. At the
same time, the planets are in orbit around the Sun, all moving
anti-clockwise as viewed from over the Sun’s north pole.
As well as having the longer orbits to complete, the planets
farther from the Sun move much slowly.
The Solar System consists of the Sun, nine recognized planets,
over 140 moons and countless small bodies such as asteroids
and comets ~ in total, the Solar System is about 9,300 billions
miles across: the planets occupy a zone extending just 3.25
billion miles from the Sun.
Neptune diameter :- 30,548 miles / Moons :- 13
Distance from Sun :- 2,791,300,000 miles
Radius at equator (Earth = 1) :- 3.88
Orbits the Sun in 164.9 Earth years.
Pluto diameter :- 1,429 miles / Moons :- 1
Distance from Sun :- 3,682,600,000 miles
Radius at equator (Earth = 1) :- 0.18
Orbits the Sun in 248.6 Earth years.
Ref No. :-DS08-012
Distance from Sun :- 1,782,500,000 miles
Radius at equator (Earth = 1) :- 4.0
Orbits the Sun in 84 Earth years.
