In the matters of the universe, Tang Zhong was completely unaware; at this moment, he was still aboard the Douluo, looking at the maps brought back by the ten Flame Dragon Soldiers!
"This is the map of the Solar System, take a good look at it!" said one of the ten Flame Dragon Soldiers beside him.
Tang Zhong examined the map carefully; it looked very ancient and was actually made of leather.
However, the things marked on it were very clear.
The Solar System is centered on the Sun and is a collection of all celestial bodies bound by the Sun's gravity. It includes the eight major planets: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, with at least 173 known satellites, 5 identified dwarf planets, and billions of small solar system bodies.
This is an introduction to the Solar System, all noted on the map below.
Looking at the map again, it appeared as a ring-shaped diagram.
It looked exactly like the Solar System as seen from Earth by satellite.
