See! This is "End of Earth" within 6.5 billion kilometers – Exploration of Science – cnBeta.COM



On January 19, 2006, New Horizon Probe was launched, and on July 14, 2015, it flew close to Pluto and then continued its long journey into space, now taking more than 4,700 days.At 1:33 am on January 2, 2019, Beijing time, he will fly across Ultima Thule, the Kuiper asteroid, which is only about 3,500 kilometers away.

At 9:56 on December 24, New Horizons took pictures of End of Earth. After about 12 hours, Earth receives this photo (three parts together):

At that time, the new horizon was around 10 million kilometers from the end of the earth and about 6.5 billion kilometers from the sun.

The Kuiper Belt is a hollow disk-shaped area with dense celestial bodies near the ecliptic plane of Neptune's orbit (about 30 astronomical units of the Sun), also known as the third area of ​​the solar system and contains billions of celestial bodies.

"End of the Earth" asteroid number 485968, astronomy named 2014 MU69, and the romantic name "End of the Earth" are the result of public voting, which means beyond the known world.

Tianya Haijiao is about 30 kilometers in diameter and the shape is irregular, found by occultation in 2017 as binary contact, or near binary systems. The color is reddish, maybe because of hydrocarbons. The solar system has been open for billions of years.

The New Horizons find great "love" on Pluto. I don't know what surprises will be found in "End of the Earth"?
