Citando:
"So far, the researchers have worked out that the planet's orbit takes it more than 120 Earth-orbits away from the Sun, and it'll get a name when enough data has been gathered to characterise its orbit properly.

Since just one-seven-hundredth of 2015 RR245's orbit has been observed, it will be a few years before its orbit is known well enough for the object to get a name.

The astroboffins will also be studying the roughly 700 km object to decide whether it's smaller and bright, or larger and dull. That will wait for better measurement of its surface properties."
