gayspacecomrnunism:quantumspork:skunkbear:Here’s the orbital period of our solar system’s 8 major planets (how long it takes each to travel around the sun). Their size is to scale and their speed is accurate relative to Earth’s. The repetition of each GIF is proportional to their orbital period. Mercury takes less than 3 months to zoom around Sol, Neptune takes nearly 165 years. fuck this gifset do you know how long i sat here waiting for fucking neptune to drag its lazy ass into the framei fucking love how all of these are described by the same two equations (the law of universal gravity and the force equation for uniform circular motion), yet none of the planets have the same rotational period or velocity.GMm/r^2 = Fg = Fc = mv^2/rLIKE THAT DESCRIBES ALL OF THEM ITS SO FUCKING COOL -- source link
