Is 'Planet Nine' actually a grapefruit-sized black hole? Big new telescope could find out

Is 'Planet Nine' actually a grapefruit-sized black hole? Big new telescope could find out

A coming sky survey will help test a wild idea — that a grapefruit-sized black hole lurks undiscovered in the outer solar system.

Over the past few years, researchers have noticed an odd clustering in the orbits of multiple trans-Neptunian objects (TNOs), which dwell in the dark depths of the far outer solar system. Some scientists have hypothesized that the TNOs' paths have been sculpted by the gravitational pull of a big object way out there, something five to 10 times more massive than Earth (though others think the TNOs may just be tugging on each other).

This big "perturber," if it exists, may be a planet — the so-called "Planet Nine," or "Planet X" or "Planet Next" for those who will always regard Pluto as the ninth planet. But there's another possibility as well: The shepherding object may be a black hole, one that crams all that mass into a sphere the size of a grapefruit.

Astronomers are already scanning the heavens for any sign of Planet Nine, and they should soon be able to hunt for the putative black hole as well, a new study reports. 

The highly anticipated Vera C. Rubin Observatory, a big telescope under construction in the Chilean Andes, is scheduled to begin a wide-ranging, decade-long survey of the southern sky called the Legacy Survey of Space and Time (LSST) in late 2022. 

The Rubin Observatory will be incredibly sensitive and scan large swaths of sky repeatedly, a combination that will provide an unprecedented wealth of data, scientists have said. For example, LSST data will allow astronomers to probe the nature of mysterious dark energy and dark matter, find and track large numbers of potentially hazardous asteroids and study our Milky Way galaxy's formation and evolution, among other things.
