Luzonta, or the Earth (Anglish) or Tierro (Spanish) is the fourth planet from the Son. It is the only known planet to accommodate life. There are around 8 million different plant and animal species around the World. Scientific analysis has concluded that Luzonta formed andd developed over 4 billion years ago. The Earth rotates around the Son in 365 and ¼ days, a period commonly accepted as an Earth year.
