    For superior planets the planet would typically move through in the night sky slower than the stars. Each night the planet would "lag" a little behind the star, in what is called prograde motion. Occasionally, near opposition, the planet would appear to move through in the night sky faster than the stars, called retrograde motion. Ptolemy's model, in part, sought to explain this behavior.…

    12) Thermonuclear reactions take place only at the suns core because in order for hydrogen to fuse and create helium, a very high temperature must be present (10 000 000 K) the high temperature at the suns core caused by the intense pressure of gravity caused by the suns mass exceeds this temperature. It is about 15 500 000 K. This temp is not present anywhere else on the sun.…

    Mercury's Astronomy

    Due to mercury being extremely close to the sun, causes its planet to have no atmosphere. If any air was ever around Mercury, it would have been within its early years and from that point to now, it is gone because of all of the heat being given off of the sun. Mercury has crazy weather issues because of the lack of atmosphere, which includes a drastic weather change within day to night.Whenever the sun touches the surface of Mercury, that is when the climate reaches its highess at 801 degrees Fahrenheit in the day time.Because of the lack of atmosphere in mercury, the Mercurial sky is black and the stars can be seen in broad daylight. The night time becomes a different situation, at this point it leaves it at a chilling climate…
