QUESTION: I saw in the newspaper that a new planet was discovered near Pluto. Is that true? Answer by Bob Loewenstein on November 8, 1995: Astronomers found what they think to be a Jupiter sized planet around the star 61 Pegasi. This star is somewhat like the sun and is about 40 light years away. If this discovery is interpreted correctly, then this is the first detection of a planet in another solar system. Our solar system still has only 9 planets. It is unlikely that another planet will be found in our solar system because there is no evidence to suggest that another one exists.
