It is radically different from Earth in other respects..
Is there a 9th planet?
Planet Nine is a hypothetical planet in the outer region of the Solar System. … Based on earlier considerations, this hypothetical super-Earth-sized planet would have had a predicted mass of five to ten times that of the Earth, and an elongated orbit 400 to 800 times as far from the Sun as the Earth.

Which planet orbit looks least like a circle?
The planet with the least circular orbit is Mercury, which has an orbital eccentricity of 0.2056. Its orbit brings it to within 46,001,200 km (0.307 AU) of the sun at its closest point (perihelion) and out as far as 69,816,900 km (0.466 AU) from the sun as its most distant (aphelion).
Why is Pluto no longer a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
