What following terms refers to an object that orbits the sun and has enough gravity to be spherical but has not cleared the area of its orbit?
The term that refers to an object that orbits the sun, has enough gravity to be spherical, but has not cleared the area of its orbit is "dwarf planet." Dwarf planets, like Pluto, meet the criteria of being round due to their self-gravity but share their orbital zone with other objects of similar size. Unlike full-fledged planets, they do not dominate their orbits.

What makes a dwarf planet a dwarf planet?
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star that is massive enough to be spherical as a result of its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite.
A planet is a?
A planet is a celestial body that orbits a star, is massive enough for its gravity to shape into a spherical or nearly spherical shape, and has cleared its orbit of other debris or objects. In our solar system, planets like Earth, Mars, and Jupiter orbit the Sun.
Why is Deimos potato shaped?
Deimos is a very small moon, so small that it does not have enough gravity to make itself spherical.
What is the criteria for something in space to be a planet?
A planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighboring region of planetesimals.
What are the properties of a planet?
A quick summary: * A planet is a naturally formed object orbiting a star or the remnant of a star. * It is large enough so that its internal gravity has formed it into a nearly spherical shape, but not large enough to cause thermonuclear fusion. * It has cleared its neighborhood of other objects like asteroids or dwarf planets.
What are the three characteristics needed to be labeled a planet?
In our solar system, a planet: 1) Must orbit the Sun 2) Must be large enough to have formed a spherical shape due to its own gravity. 3) Must have cleared the neighborhood of its orbital path of other bodies.
What does earth and mercury in common?
They are both planets and in that respect, they are:massive enough so that they are approximately spherical as a result of their own gravity,not so massive as to generate thermonuclear fusion, andhave cleared their neighbourhood of planetesimals.
What makes a dwarf planet a dwarf planet?
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star that is massive enough to be spherical as a result of its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite.
Is Pluto massive enough so that its own gravity makes it into a spherical round shape?
Yes, Pluto is massive enough for its own gravity to pull it into a nearly spherical shape. Although it is not a perfect sphere due to its relatively small size and irregular composition, its gravity is strong enough to overcome its rigid structure and mold it into a round shape.
State four requirements needed to be considered a planet?
To be considered a planet, an object must orbit the Sun, be spherical in shape due to its gravity, and have cleared its orbit of other debris. It should also not be a satellite of another object.
How do planets develop their spherical shape?
Gravity pulls the asteroids into spheres when they get big enough.

Why does Eros have an irregular shape instead of a spherical shape?
Jupiter's gravity It is not massive enough to pull itself into a spherical shape like something the size of the moon or Earth.
Why do planets look like a perfect circle from a distance?
It's part of the definition of "planet". An asteroid or meteor can have any shape, because its gravity isn't great enough to crush it into a mostly-spherical shape. But planets ARE massive enough that they have to be spherical; their gravity forces them into that shape. If their spin is fast enough, the equatorial regions will bulge out, such as with Earth and especially with Jupiter.
What does a asteroid have a irregular of?
If the asteroid is large, its own gravity will pull it together, into a more or less spherical shape. With smaller asteroids, the gravity is not large enough, and the shape will be irregular.
