What are the three characteristics of a planet?

Answer 1

The three qualifications for a planet are:

1. It orbits the parent star.

2. It has hydrostatic equilibrium (roughly spherical shape) caused by the gravitational forces.

3. It has cleared its path of orbital debris. (This one is hotly contested.)

Answer 2

The earth or a planet that resembles the earth in its physical characteristics. The terrestrial planets in the solar system are the earth, mercury-in-roman-religion-planet-nearest-to-the-sun, venus, and mars. These planets are approximately the same size, with the earth the largest. They are considerably denser than the jovian-planet, ranging from a specific gravity of 4 for Mars to 5.5 for the earth. Because they spin less rapidly than the Jovian planets, the terrestrial planets are less flattened at their poles.

Answer 3

The elements of Terrestrial Planets are made up of rocky ground or land, as distinct from water or air.

They are also planets nearest our sun ,Venus,Mercury or Mars that resemble Earth in substance and density

Answer 4

IT HAS TO HAVE . . . A SPHERE SHAPED BODY IT HAS TO BE AN INNER OR AN OUTER PLANET ORBITS THE PARENT STAR IT'S CLEARED IT'S SPOT OF ORBITACLE DEBRIS. IT HAS HYDROTASTIC EQUILIBRIUM (Roughly spherical shape)CAUSED BY THE GRAVITATIONAL FORCES.

Answer 5

Made of solid material, small, closest to sun.

Answer 6

1. rocky

2. Gassy

3. Stupid

4. Dumb

5. You love men

Answer 7

They are in direct orbit around the sun, they are large enough to be approximately spherical (achieving hydrostatic equilibrium) and have cleared their orbit of other major bodies.

Answer 8

A planet must orbit around a star, have sufficient mass to maintain a nearly round shape, and have cleared its orbital path of other debris.

Answer 9

iron-nickel core
