How are the planets orbit around the sun incressing or decressing over time?

Question

Is the earths orbit around the sun getting faster or slower?
How about jupiter or saturn?

Answer 1

I don't think the orbits have changed at all.

If anything our sun will expand from it's current size, engulfing the inner four planets of this solar system. (Don't worry, not in this lifetime) lol

Answer 2

To my knowledge, there is no appreciable increase or decrease among the planets to concern yourself with. There are variations due to gravitational effects of planets on other planets, the most pronounced used to be that of Pluto as its more elliptical orbit took it in and out of Neptune's orbit, sometimes passing nearby. But by and large, these variances are insignificant because of the vast distances between each planet's orbit and its next nearest neighbor. They also tend to average themselves out.

Should the Sun lose a significant portion of its mass as predicted in the last part of its life-cycle, then the planets will have less gravitational force being exerted upon them and they will tend to gradually drift out into slightly larger orbits.

Answer 3

The Orbit of all the planets is gradually decaying so that they gradually orbit closer and closer to the sun which actually makes them complete a solar orbit faster, so the solar year for each planet gets shorter. Eventually the great Yahoo trog will return and swallow them all.

Answer 4

slower and then after the demise of the sun hurling off into deep space.
