Paper: An Analysis of the Planets Discovered by the Hubble Space Telescope

Astronomers have based this conclusion on temperature measurements. Using a spectrum to measure red and blue light emitted by TMR-1C, temperatures are obtained. Temperatures are estimated to be higher than what was predicted a young giant planet would be. While this test is not absolute, chances are great that this is a background star that appeared to be a planet because of its distance from the Hubble telescope and interference of space dust. (Savage 2000) However, since that first suspected sighting, many other extrasolar planets have been found. In fact, seven extrasolar planets have been identified recently, raising the number of confirmed extrasolar planets to 40. (Planet Hunters) These planets for the most part have been the size of Jupiter or larger. The most two recent planets discovered have broken the mold. Geoff Marcy of the University of California at Berkeley and Paul Butler of the Carnegie Institution of Washington discovered two new approximately 110 light-years form Earth. In mass, these planets are approximately the size of Saturn. Marcy and Butler both suspect the existence of a third planet in this same vicinity. As more and more extrasolar planets are discovered, their size seems to be getting smaller. Astronomers are looking forward to discovering planets the size of Earth in the near future.
