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 two measurable properties directly tell us the size and shape of a planet's orbit?
The semi-major axis (size) and the eccentricity (shape).
What is the size and shape for Venus?
If you mean the shape of the orbit, it's an ellipse.
Does planet shape life or life shape the planet?
Both are true there is an interdependance.
Does the mass of a planet equal the size?
No, the mass of a planet does not equal the size of that particular planet.
Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
What affects the shape of the planet's orbit?
The size of the planet along with the gravitational force within the planet.
What affects the shape of a planets orbit?
The size of the planet along with the gravitational force within the planet.
What 2 factors determine a pearls worth?
size, and shape
What two measurable properties directly tell us the size and shape of a planet's orbit?
The semi-major axis (size) and the eccentricity (shape).
What factor determine the location and size and shape and direction of the surface current gyres?
Four factors that determine the location, size, shape, and direction of a gyre are wind, gravity, Coriolis Effect, and topography.
What is a limitation of a model of the solar system using styrofoam balls?
model limitations: · You are unable to determine the size of the planets · You are unable to measure the length between each planet · You can not determine the speed which the planet is rotating at · You can not determine the speed that the planet is travelling around the sun · You are unable to determine the direction that the planet is turning · You are unable to determine the direction the planet is going around the sun · You can not measure the axis that the planet is leaning on
What are two factors that determine the proporties of a hydrocarbon?
This is a little vague, but size and shape?
What is the size and shape for Venus?
If you mean the shape of the orbit, it's an ellipse.
What describes a rock's texture geologists determine?
The size shape and pattern of the rocks grains
Does the shape or size of a ball effect the bounce of it?
Does the size of the ball determine how high the ball will bounce? I need the answer for a science project.
How big will a planet be if it is located far from the sun?
The size of a planet is not related to it's distance from the sun. Planet mass and orbital velocity are factors that determine it's distance from the sun.
If you know the size of an asteroid you can determine its density by?
determining its mass from its gravitational pull on a spacecraft, satellite, or planet.
