Q. Is there a planet beyond Pluto that could be in our solar system?
A. Scientists pretty muck have discounted the presence of what used to be thought of as a 10th planet, called Planet X. Scientist are looking at data that they believe show there are tow planets, and possibly more, outside our solar system but still in our galaxy, the Milky Way. These planets have not been seen, but experts believe the planets orbit a neutron star, which sends out radio waves. The planets are thought to be in the general direction of the constellation Virgo.
