Bright planets can seem to jump around because of an optical illusion called the autokinetic effect.
Under normal conditions, when there are stationary objects your field of vision, your brain compensates for the effect, and you do not notice it. However, when you look at a bright, isolated object, such as a planet in the sky, your brain can mistake the movement of your eye for movement in the object. Atmospheric effects can also make stars look unsteady, and can cause bright stars to seem to change color. Dust and air molecules in the Earth's atmosphere tend to scatter blue light around. When light from the Moon comes through the dusty atmosphere, some of the blue light is removed this way, leaving behind more reddish light so when atmospheric conditions are right the Moon can look yellow, orange, or even red.
