Which planet would have the slowest or longest orbit around the sun?
Neptune has the slowest and longest orbit. It has a radius of 30 astronomical units (i.e. 30 times as far as the Earth), and it takes 165 years to go round once. So it has been round almost exactly once since it was discovered in 1846. It was discovered officially on September 24 1846, and it completed its first revolution since discovery on June 30 2011.
When will the dwarf planet Eris orbit around the sun?
It is currently in orbit and has been since it was created.
Why weren't Ceres considered a planet?
Ceres is not considered a planet, since it does not dominate its orbit. There are other sizable objects at that distance from the sun, in orbit around the sun. It is a dwarf planet though.
What must a planet have which a dwarf planet doesn't?
A planet: 1) Orbits the Sun or some other star 2) Gravity has to shape it into a sphere & 3) Have an orbit that does NOT link up to another planet's orbit A dwarf planet is classified if it does not have one of these 3 things. Reason 3 (like most other dwarf planets in our Solar System) is what makes Pluto a dwarf planet (since some of it's orbit links up to Neptune's orbit)
What is the exact date of the planet mercury's discovery?
This is impossible to determine, since Mercury has been known and recorded since antiquity.
Which planet has not completed and orbit around the sun since its discovery?
Neptune and Pluto.
What planet completed it's first revolution around the sun since discovery?
Neptune was discovered in 1846 and it takes about 165 Earth years to orbit the Sun. So, it has just completed one orbit since discovery.
Which planet has not completed an orbit around the sun since its discovery?
Neptune (the eighth and outermost planet) was discovered on September 23, 1846. It takes 164.79 Earth years to complete one orbit and will therefore only complete its first orbit since its discovery in 2011. It is also worth noting that while Pluto is not longer regarded as a planet (it is now a minor planet) it was discovered in 1930 and takes 248.09 Earth years to complete an orbit.
Which planet will complete its first orbit since its discovery in 1846?
Neptune. It takes 165 years to make one orbit.
Which planet will complete it's orbit since it's discovery in 1846?
Neptune. It was discovered in 1846 and takes nearly 165 days to make one orbit of our sun.

Which planet will complete its first orbit since 1846?
Neptune, the furthest planet from our sun.

Ceres is not considered a planet, since it does not dominate its orbit. There are other sizable objects at that distance from the sun, in orbit around the sun. It is a dwarf planet though.
What is the orbit of a planet?
An ellipse. (Kepler's first law of planetary motion) Since the plants do not orbit in a perfect circle. They orbit in a oval shape.
