139 new small planets discovered at the edge of our solar system

Astronomers have discovered 139 new Trans Neptune objects (TNOs) At the far corner of our solar system. This discovery is given in the Astrophysical Journal Supplement Series. Along with this, a new discovery system has also been introduced, which will benefit for the discovery of new planets and especially in the research on the predicted ninth planet.

TNOs are small planets that orbit the Sun, traveling an average distance from the planet Neptune. The ninth planet is projected to exist in the outer part of our solar system. On this, Professor Gary Bernstein of the University of Pennsylvania said that the new TNO discovery depends on how much sky you are able to see.

Researcher Pedro Bernardinelli used four years of data from the international project ‘Dark Energy Survey’ which has a record of 700 million points in space. The researchers separated stars, galaxies, and supernovae from these points. Still 2.2 crore objects were present. 400 of these marked possible bodies that had been visible for six or more nights.  After analyzing the photos for several months, 316 TNOs were listed, Of these, 139 were seen for the first time.

So far, about three thousand TNOs have been recorded in the solar system, including Pluto. Astronomers estimate it is 10 percent of the TNO actually present. Many TNOs are so far away from Earth that it takes 20 thousand years to make one round of the Sun.
