About 3,000 objects, ranging from small asteroids and comets to dwarf planets, orbit our Sun beyond Neptune. Pluto is the one you’re most likely to recognize. Now 139 previously unknown minor planets have been spotted in the outer reaches of the solar system. One could be the hypothetical Planet 9 – a real object that perturbs other orbits, not the silly end-of-the-world theory.
Starting with 7 billion “dots” in the Dark Energy Survey’s data, they wittled the possibilities down to 139. The data manipulation is as amazing as the worlds probably are. We won’t know for a very long time, so enjoy images of Pluto instead.
Dwarf planets aren’t all they found – not even the main goal.
The survey used the 520-megapixel Dark Energy Camera—based at the National Science Foundation’s Cerro Tololo Inter-American Observatory in Chile—to record data from more than 300 million galaxies. Newsweek
There may be a lot of objects out there, but space is very big. Pluto isn’t likely to host a block party.
BTW – that was a reference to Planet 9 in outer space, not Plan 9 from Outer Space. lol
