It is Venus because according to the earth science reference tables, its eccentricity is closest to zero. The more closer to zero, the closer to a perfect circle it is.
I hope i answer your question. I'm an 8th grader who was also looking for the answer, but i found it somewhere else. I usually use WikiAnswers too. So I felt like being helpful so here is your answer(: From an 8th grader in New York.
What else can I help you with?
Which planet has the roundest orbit?
Venus has the most nearly circular orbit of all the planets in our solar system. Its orbit has the least eccentricity, meaning it is closest to being a perfect circle.
Which planet's orbit is most like a circle?
Venus has the most circular orbit among the eight planets in our solar system. Its eccentricity, which measures how elongated an orbit is, is the closest to zero, making it almost circular.
Which planet has an orbit that is closest to a perfect circle?
The earth's orbit is almost a circle, but not quite. It is elliptical, but the difference between the closest and farthest points is less than 4%. This is such a small difference that it would look like a circle to most people. Astronomy books often show misleadingly exagerated elliptical orbits.
What shape do planets trace as they orbit around the sun?
Planets orbit the sun in the shape of an ellipse, which is an elongated circle similar to an oval. When it was first discovered that the Sun is the center of the solar system, it was thought that all the planets had a circular orbit, but the calculations didn't fit.
Which planet has most elliptical orbit?
Mercury has the most elliptical orbit among the planets in our solar system. Its orbit is significantly elongated, with the eccentricity of 0.2056, which means that it deviates the most from a perfect circle compared to other planets.
Which planet has the roundest orbit?
Venus has the most nearly circular orbit of all the planets in our solar system. Its orbit has the least eccentricity, meaning it is closest to being a perfect circle.
What point in a planets oribits is closest to the sun?
perihelion is the point in a planets orbit when it is closest to the sun
What planets orbit Jupiter?
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.
How does planets circle around the Sun?

Which planets orbit faster?
Closest to the sun

What is planet Jupiter's orbit?
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.

Why do the planets orbit the sun in a circle?
The gravitational pull.
Name of planets orbit closest to the sun?
The Inner Planets: Mercury, Venus, Earth and Mars
What is the name of the circle that the planets go around?
If you mean the trajectory of the planets around their parent stars, it is called the orbit, and it is not a circle but an ellipse
Does mercury have the largest orbit?
Mercury has the shortest orbit of all the planets because it is the closest planet to the Sun.
