Document Summary
How did everything form? is planet formation around stars common? the directions of rotation and revolution are very similar, with a few notable exceptions: note how venus, uranus, and pluto all have odd rotations, and that. Pluto"s orbit is also unusual (highly inclined: arrows: direction planets orbit around the sun (all in same direction, arrow going through planet: axis of rotation, direction of rotation: right thumb rule. Made mostly of hydrogen and helium gas (plasma) Every second converts 4 million tons of mass into energy (for last 4. 5 billion years and will be doing it for another 5 million years) Made of metal and rock, large iron core. Very hot and very cold: 425 celsius in day, -170 celsius at night *depends on the side facing sun. Nearly identical in size to earth; surface hidden by clouds. Hellish conditions due to an extreme greenhouse effect. Even hotter than mercury 470 degrees day and night.
