Bugs

• The camera doesn't center exactly on the planets. Likely due to floating point precision errors. A float 32 is not precise enough to accurately represent the orbits of the planets.
• Planets jiggle around when zoomed in, only when locked to Uranus and beyond. Likely due to floating point precision errors.
