I was doing some more studying of astronomy topics, while watching a related television program. How the Universe Works is on right now, with this episode entitled as Planets From Hell! I got caught up in listening to the details about one world that seems to have been sparking the interest of astronomy and extraterrestrial researchers for many years. The Science Channel is continuing to spark interest in what exists beyond what we know about our universe, and the possibilities of all that could be out there, beyond what we think that we know.
Details were given about an extrasolar planet that has been entitled COROT-7b. It orbits the star COROT-7, which is found in what we have labeled as The Monoceros Constellation. This constellation is not easily observable, though it has been recognized to contain stars that include V838 Monocerotis, along with the binary systems called Plaskett’s Star and Epsilon Monocerotis. Corot-7b has been calculated to be 480 light years away from us!
This planet is being described as Earth-like. However, it is not too much like Mom, as Corot-7b sits on top of it’s host star at a distance that is sixty times closer than Earth is to The Sun. That acute proximity makes Corot-7b situated within a roasting, oven-like position. The daylight temperature of the world is estimated to average near to 3,600º Fahrenheit!
As Corot-7b is so close to Corot-7, it is believed that the day side of the planet is molten lava. One studying scientist believes that this planet could have been larger, yet it was reduced in size because the hear of it’s star boiled off much of the planet! An interaction between this planet and it’s star is being revealed through what is called tidal migration. Corot-7b loses mass due to the heat of Corot-7. Plus, the gravitational interaction between the planet and the star causes tidal migration, which increases solar tides of Corot-7, while slowing the orbital speed of Corot-7b.
Again, something interesting I found while doing studies of recent online astonomy postings. It is extremely fascinating to recongize that all of that is out there, and there is so much more that we do not know about! One day, maybe even sooner than we think, we will be able to venture into further areas of The Milky Way, studying new objects, and boldy going where no one has gone before!
