Dear MEL Topic Readers

The hunt for Planet X turns up a new solar system object

We know so little about our solar system, our galaxy, and the universe.

Our solar system is believed to have been formed some 4.6 billion years ago. There are eight planets, five dwarf planets, and two belts, one between Mars and Saturn and the other outside of Neptune’s orbit in the solar system.

Astronomers have been searching for another orbing object, called Planet X, outside the current boundary of our solar system. Though the planet hasn’t been discovered yet, a dwarf-like object was found at around 2,000 times the distance between us and the sun. It is thought to take as long as 40,000 years to go around the sun. As you know, it takes only a year for Earth to orbit the sun and 165 years for the farthest planet Neptune.

This new dwarf planet was nicknamed the Goblin as it was first observed during the Halloween period. What is significant about this discovery is that the move of the Goblin seems to be strongly influenced by nearby massive force, presumably Planet X.

Enjoy reading about this exciting discovery in our solar system.
