A couple of astronomers are excited because they think there might be a ninth planet in the solar system:

Scientists Find Hints Of A Giant, Hidden Planet In Our Solar System The astronomer whose work helped kick Pluto out of the pantheon of planets says he has good reason to believe there's an undiscovered planet bigger than Earth lurking in the distant reaches of our solar system. The astronomer whose work helped kick Pluto out of the pantheon of planets says he has good reason to believe there's an undiscovered planet bigger than Earth lurking in the distant reaches of our solar system. That's quite a claim, because Mike Brown of Caltech is no stranger to this part of our cosmic neighborhood. After all, he discovered Eris, an icy world more massive than Pluto that proved our old friend wasn't special enough to be considered a full-fledged planet. He also introduced the world to Sedna, a first-of-its-kind dwarf planet that's so far out there, its region of space was long thought to be an empty no man's land. Now Brown has teamed up with Caltech colleague Konstantin Batygin to do a new analysis of oddities in the orbits of small, icy bodies out beyond Neptune. In their report published Wednesday in The Astronomical Journal, the researchers say it looks like the orbits are all being affected by the presence of an unseen planet that's about 10 times more massive than Earth — the size astronomers refer to as a super-Earth. |

But of course, the creationists are way ahead of them:
Detecting the Hidden Mass That Comets Feel In the last 920 years, almost 1,000 different comets have been observed accurately enough to calculate these five numbers. Surprisingly, pairs of comets have very similar sets of numbers. Could some “strange pairs” really be the same comet on two successive orbits? The estimated orbital period, the time to complete one orbit, for each member of the “strange pair” is so extremely long that they should not be the same comet. However, if the comets were all different, the chance of any two randomly selected comets having such similar orbits is about one out of 100,000. The chance of getting at least 13 “strange pairs” from the vast number of possible pairings is about one out of 7,000. If the solar system’s mass has been slightly underestimated, orbital periods are much shorter, and some “strange pairs” are almost certainly the same comet. Other reasons are given in this chapter for believing that a slight amount of extra mass exists in the solar system. |
