U.S. astronomers hunting for "Planet Nine" have instead stumbled on what appears to be a new dwarf planet in the solar system's outer reaches.

It's an evocative idea that has long bedeviled scientists: a huge and mysterious planet is lurking in the darkness at the edge of our solar system, evading all our efforts to spot it.

Using the Dark Energy Camera astronomers have found a packed stellar nursery of infant stars in the dark nebula in the 180-light-year-wide Circinus West molecular cloud.

The supposed interstellar fireball detected over the Pacific Ocean in 2014 probably came from within our solar system, according to new statistical modeling of the meteor and others similar to it.

Thus, in the planetary region of our solar system, defined as a sphere with the radius of Neptune’s orbit, there must be about 10,000 similar objects, of which ‘Oumuamua was only the first one ...

Called "2I/Borisov" (formerly "C/2019 Q4" or "gb00234"), the object appears to be following a path originating from outside the solar system. It's expected to pass near Mars in October.

Artist’s impression of ‘Oumuamua, the first known object from another star to visit our solar system. A second candidate interstellar visitor, a comet designated C/2019 Q4 (Borisov), has now ...

It’s thought to be about a quarter-mile long, and about 10 times longer than it is wide. That makes it unlike any asteroids seen in our Solar System, none of which are so elongated.
