Chapter 484 An Extraterrestrial Battleship the Size of Earth

• Indeed, what Lu Chen saw through the telescope was a planet. The planet was not one of the eight planets in the solar system; it was also not Pluto, which was mercilessly excluded from the solar system before it was no longer considered a planet. It was a whole new planet, undiscovered and unrecorded by any human being up until now.
• It had sufficient mass to assume hydrostatic equilibrium and clear other smaller celestial bodies around its orbit. It fulfilled every criterion of astronomers’ definition for a planet from every aspect. Yet, it had not been discovered by humans due to its relatively small size. Moreover, since it was located very far away from the Sun, light from the Sun could barely reach it.
• Based on Lu Chen’s preliminary calculations, its mass was about 1.5 times that of Earth. It was a terrestrial planet, orbiting around the Sun at an extremely low speed. The duration it took to fully orbit the Sun in a cycle was 732 years.
