I was stunned recently by this report that there may be a massive new planet that we did not know about in our very own Solar system. I thought this must be a hoax report but apparently it is being considered as a serious possibility.
The hunt is on for a gas giant up to four times the mass of Jupiter thought to be lurking in the outer Oort Cloud, the most remote region of the solar system. The orbit of Tyche (pronounced ty-kee), would be 15,000 times farther from the Sun than the Earth’s, and 375 times farther than Pluto’s, which is why it hasn’t been seen so far.
But scientists now believe the proof of its existence has already been gathered by a Nasa space telescope, Wise, and is just waiting to be analysed.
You would have thought that our knowledge of our own stellar neighborhood was complete but apparently not. The suggestion that Tyche existed was first made as far back as 1999 but not everyone is persuaded that it exists.
We should know with greater certainty either way by 2012. This is what makes science so much fun. There are always new discoveries to look forward to.
