All orbits are elliptical.
Some orbits, like Earth's, are almost circular without much eccentricity in the orbit. The orbit of Eris is HIGHLY eccentric, with a perihelion of 38 AU and aphelion of 98 AU. The orbital period is 557 years.
3.436 km/s

Eris has quite an excentric orbit; the distance from the Sun varies between 37.77 AU and 97.56 AU.
It takes more than twice as many years to orbit the Sun as Pluto, about 560 Earth years.
it is 96.6 au from the sun, which is 1.44511668 x 10 meters.
Yes. All planets and dwarf planets orbit the Sun

25.9±0.5 hr, according to the Wikipedia article.
The Moon revolves round the Earth and rotates on its own axis once every 27.3 days.
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
Mercury rotates once in about 58.6 Earth days.
A Mercurian "day" the (time it takes it go spin once on it's axis) is equal to 58.65 earth days. Mercury turns on it's axis very, very slowly.
25 days
Venus rotates once in 243 days.
25.9±0.5 hr, according to the Wikipedia article.
Twenty-eight days. As the moon orbits the Earth - it rotates once on its axis.
365 days in a year 366 days in a leap year.

The Moon revolves round the Earth and rotates on its own axis once every 27.3 days.
One. Well, not QUITE one, to be exact. It takes 23 hours 56 minutes for the Earth to turn precisely once on its axis.
Mercury is weird. It circles the sun every 88 days, and takes 58.6 days to rotate once on its axis !That's 1,406 hours .
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
The Sun rotates on its axis once every 25.05 (Earth) days.
Yes it does. It takes 25.05 earth days to revolve on its axis once.
