Planets, by definition are all approximately spherical in shape, though their axial rotation often means that they are oblate spheroids (look like `squashed spheres`, longer across the equator than from pole to pole).
The size of the planets varies;
Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter
Venus' diameter = 12104km or 0.9488 x Earths
Earth's diameter = 12756km
Mars' diameter = 6794km or 0.5323 x Earths
Jupiter's diameter = 142,984km or 11.21 x Earths
Saturn's diameter = 120,534km or 9.45 x Earths
Uranus' diameter = 51,114km or 4.01 x Earths
Neptune's diameter = 49,532km or 3.88 x Earths

What is the shape of dense bodies the size of planets or larger?
Approximately "spherical".
What affects the shape of a planets orbit?
The size of the planet along with the gravitational force within the planet.
How did gravity relate the shape and size of the universe?
because the suns gravitational pull is so large that the planets stay close to together
What was the role in gravity on shaping your universe?
maintains planets in their orbits; makes stellar bodies round
What effects does gravity have on planets orbit?
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
What is the shape of dense bodies the size of planets or larger?
Approximately "spherical".
What is the shape of dense body is the size of planets or larger?
Approximately "spherical".
What creates stars and planets?
Gases and rocks that form together to form a bigger shape or size
What affects the shape of a planets orbit?
The size of the planet along with the gravitational force within the planet.
Why do each of your planets in the solar system look alike?
They don't because their different in size, shape, and color
Why planets are of regular in shape while meteors are irregular in shape?
Because of their larger gravity, AND their larger size. Larger gravity will allow smaller hills or other irregularities; larger size means that an irregularity of a certain size will smaller, compared to the size of the planet.
How To determine the size and shape of a planet?
Planets are always approximately spherical in shape. Because of their rotation, they do bulge slightly at the equator, creating a shape called an oblate spheroid. This can be observed directly with telescopes. As for the size of planets, we have observed them a lot, not just with telescopes but also with planetary probes, but in addition to that, the way satellites orbit a planet (their distance and speed) tells us about the planet's gravitational field, and hence, its mass. Most planets have satellites.
What is the typiccall shape of the planets?
Planets are all spherical.
What are the characterstics of Planets?
all planets have a circular shape
What are the different planets?
Mainly size, density, distance from other planets, distance from the nearest star, existence of satellites, age, shape, (The Earth is flattened on its poles.) and many other features.
Which planets has more of a spherical shape?
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
How did gravity relate the shape and size of the universe?
because the suns gravitational pull is so large that the planets stay close to together
