"Planet X" might actually exist — and so might "Planet Y."

At least two planets larger than Earth likely lurk in the dark depths of space far beyond Pluto, just waiting to be discovered, a new analysis of the orbits of "extreme trans-Neptunian objects" (ETNOs) suggests.

Researchers studied 13 ETNOs — frigid bodies such as the dwarf planet Sedna that cruise around the sun at great distances in elliptical paths.

The morning sky will play host to a spectacular gathering of solar system objects grouped closely together tomorrow (Nov. 22), but it won't be easy for observers on Earth to see it.

The sun, moon, three planets and the dwarf planet Ceres will all appear within a 20-degree span of sky. (For reference, your clenched fist held up to the sky measures about 10 degrees across.) Mercury and Saturn will be just west of the sun and new moon, while Venus and Ceres will be to the east. Unfortunately, the bright sun will wash out the beautiful "conjunction," but interested observers can still use a planetarium software program like Starry Night to check out the stunning event.
