NASA is planning to launch the Mars 2020 robotic rover to the one of the mysterious planets which is sometimes called Red planet.
New simulations show that Earth’s moon is not only unique in the solar system, but can also be rare throughout the Universe. Studies show that less than 10 percent of terrestrial planets may have a satellite large enough to provide the stability life needs to develop. Earth spins around its orbital axis, changing its angle toward the sun. The moon recognized as a significant stabilizer of Earth’s orbital axis. Without it, astronomers have predicted that Earth’s tilt could vary as much as 85 degrees. In such a scenario, the sun would swing from being directly over the equator to directly over the poles over the course of a few million years, a change which could result in dramatic climatic shifts. Moon is still a matter of debate. However astronomers look for systems like our own.
