I only want to label in my legend the moon and the earth, so how do I get rid of the rest of the colours? Is it possible to only show the earth (yellow) and the Moon (green) in the legend?

You can use the handle returned by plot() with legend() to only show specific legends. For example

hold on;
p(1) = plot(rand(1,10));
p(2) = plot(rand(1,10));
p(3) = plot(rand(1,10));
p(4) = plot(rand(1,10));
p(5) = plot(rand(1,10));
legend(p([3 5]), {'legend3', 'legend5'});
