Quoting michaelwhittaker,

According to recent astronomical discoveries going off the fact that all 8 of our planets orbits r considered round. They have found that only 1 in 1000 planets have round orbits. The rest r eliptical.

Here's a philosophical, no a rhetorical question for you. How far off round does a planet's orbit have to be to be considered elliptical. I just checked wikipedia and found:

A circular obit is one where the eccentricity (orbit deviation) is 0.

A Kepler orbit is one where the eccentricity is between 0 and 1. (non-inclusive). This term comes from Johannes Kepler of the early 1600s.

Parabolic escape orbits and hyperbolic orbits, from what I was able to understand, seem to be one shot occurrences, since Wikipedia describes them as cases where the orbiting object escapes the orbited object. I really don't understand why these are called "orbits", but I don't think they are germane to our current discussion.

The use of "round" in reference to a planet's orbit is not used, but "circular" surely fits what you are describing.

However:

Mercury has a Kepler orbit, with an eccentricity of 0.205

Venus has a Kepler orbit, with an eccentricity of 0.0067

Earth has a Kepler orbit, with an eccentricity of 0.0167

Mars has a Kepler orbit, with an eccentricity of 0.093

Jupiter has a Kepler orbit, with an eccentricity of 0.0488

Saturn has a Kepler orbit, with an eccentricity of 0.0557

Uranus has a Kepler orbit, with an eccentricity of 0.044

Neptune has a Kepler orbit, with an eccentricity of 0.0112

And, just for comparison,

Haley's Comet has a Kepler orbit, with an eccentricity of 0.967

As you can see, all eight of Sol's planets except Mercury have a small orbital deviation, all less than 0.1, but none of them are considered circular.
