As the search for a hypothetical, unseen planet far, far beyond Neptune's orbit continues, new research provides additional support for the possible existence of such a world and narrows the range of its parameters and location.

Beyond its distance and estimated size, astronomers know little about the distant object V774104. Within a year, they hope to determine the characteristics of its orbit around the Sun (small yellow dot at center). The outermost pink circle denotes Neptune's orbit.
