The first swiveling orbit suggest all orbits do but in a very small way. The swivel of Mercury came from the difference of strength of gravity by distance that is changing in between gravity centers.. Sun and first planet. Orbits are in slightly different gravity strengths this determines swivel degree which can be too small to see at this time but by required time we might begin to see... Mitchell Raemsch

So, if they are not going to give me credit- maybe they will give you credit- good luck.

Yes, the eight planets have reasonably circular orbits except for Mercury. But most large asteroids and dwarf planets like Pluto do not have circular orbits, and there are more of them than planets. Moreover, there are over 700 comets that have been observed, and NONE of them have an orbit that is anywhere close to circular. Part of this is selection bias -- to be notable an orbiting object must be observed. But if an inner solar system object had an eccentricity comparable to a long-period comet (0.97-0.99), it would never have been observed by humans because it would have melted or broken up long ago (coming so close to the sun). So the only objects in highly elliptical orbits are far from the sun and have periods of hundred to thousands of years (or longer, c.f. the newly discovered "Planet 9"); Halley's comet is a rarity (period only 75 years). Mathematically, the set of circular orbits is minuscule within the set of all possible orbits. That is, the vast majority of all possible orbits are not circular at all. In addition, most extrasolar planets whose eccentricities are known have values more than ten times that of earth. It's remarkable (and sad) that you have opinions on so many things you clearly know nothing about. You really should learn how to recognize when you don't know something. Tom Roberts

The increase in speed is micro for the Earth orbiting around the sun. Look at the orbital strength of gravity only accelerating by the smallest difference that creates ellipses (that swivel) Mitchell Raemsch

Mercury is small and closest and is unstable.

Did I mention all planets travel on a different ecliptical plane also... and this is why we perceive elliptically oval observations.

It's best to freeze instantaneous amounts of time and then measuring the change through time, astronomically isn't it?
