Cosmic objects with strange orbits discovered beyond Neptune

#1

Post by smp »


From Space.com:
"A six-year search of space beyond the orbit of Neptune has netted 461 newly discovered objects.

These objects include four that are more than 230 astronomical units (AU) from the sun. (An astronomical unit is the distance from the Earth to the sun, about 93 million miles or 149.6 million kilometers). These extraordinarily distant objects might shed light on Planet Nine, a theoretical, never-observed body that might be hiding in deep space, its gravity affecting the orbits of some of the rocky objects at the solar system's edge."

This is the second article I've seen recently describing results from data mining the DES data set.
The findings are exciting, the researchers wrote in their paper, because the Dark Energy Survey wasn't meant as a search for trans-Neptunian objects. Its goals were to characterize the theoretical dark energy that affects the universe's accelerating expansion. Nevertheless, the data from the survey contains 20% of all currently-known TNOs, the researchers wrote, covering an eighth of the sky.
That is a significant sample of the sky and I hope other researchers can make equally successful use of it.
Any metaphor will tear if stretched over too much reality.
