One of the favorite topics of our news is about moon landing. So, on this day (on September 20, 1970) the Soviet Union's Luna 16 moon probe landed on the moon.
Astronomers have found a mysterious object at the edge of our solar system. Astronomers have different kinds of ideas about this strange object. Researchers hoped that such a strange world is lying in the dark at the edge of our neighborhood, but no proof has yet been discovered.
The new discovered mysterious object is called 2015 TG387. It is probably a small dwarf planet at just 300km across, and is extremely far away. It is currently lying about two and a half times further away from the Sun than Pluto is.
“This is a real victory for little projects. Our team had less than 0.3 percent of the budget of large international projects. We didn’t even have enough money to build a second dome to protect our second telescope! Yet we still managed to make a discovery that is impossible for the big projects,” said NAOJ astronomer Ko Arimatsu.
“These distant objects are like breadcrumbs leading us to Planet X,” said Scott Sheppard, the Carnegie astronomer who helped lead the research. “The more of them we can find, the better we can understand the outer Solar System and the possible planet that we think is shaping their orbits — a discovery that would redefine our knowledge of the Solar System’s evolution”.
The scientists would like to understand how it would be affected by the hypothetical Planet X. They discovered that a mysterious object— a huge Super-Earth on a very wide orbit — fit with the way that their new find was moving through the solar system.
As scientists indicate the object is one of the strangest things that astronomers have ever detected within our own solar system; The researchers said.
“We think there could be thousands of small bodies like 2015 TG387 out on the Solar System’s fringes, but their distance makes finding them very difficult,” said the University of Hawaii’s David Tholen. “Currently we would only detect 2015 TG387 when it is near its closest approach to the Sun. For some 99 percent of its 40,000-year orbit, it would be too faint to see.”
