What are two criteria needed for a space object to be a planet?

There are three things needed to qualify as a planet. A body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.

What is the white planet-like object that rotates around the earth in space?
The moon.
What is orbital point?
Oribtal points are any location in space where an object may freely orbit around a planet, or other astral object, without falling to the planet below.
What is a hole in the surface of a moon or planet formed by the impact of a space object is called?
A crater
What is an alliteration for a planet?
Spinning Space Sphere Orbiting Object Rotating and revolving Rock
A 50.0-kilogram object in outer space is attracted to a nearby planet with a net force of 400. newtons. What is the magnitude of the object's acceleration?
8
What are two criteria needed for a space object to be considered a planet?
The IAU has declared that a stellar object must be spherical or circular in shape and must orbit the Sun. Oh the shape of the object must be a result of its own gravitational mass.
Why the criteria of the Pluto do not match with other planets?
If by this question you mean why Pluto is no longer an official planet, it's because it is not the dominant object in its region of space.
Why is it a planet?
A planet is a non luminous object revolving a star in space.
Is cloud a celestial object?
No. A celestial object is an object in outer space, such as a planet, star, meteor or comet. Clouds are not in outer space, therefore they are not a celestial object.
Object in space that begins with letter E?
The planet Earth.
Is the moon the nearest planet to the sun?
No. Mercury is the closest planet to the sun. The moon is not a planet and is the closest object in space to Earth.
Does an object floating far in space have any mass?
It will have the same mass no matter where the object is: free floating out in space or on a planet or on a powerful rocket rapidly accelerating.What will be different is weight, which is only observed while the object is experiencing forces: free floating out in space the object has no weight, but either sitting on a planet or accelerating on a powerful rocket the object does have weight.
The initial speed that an object needs before it can leave a planet and go into space is known as?
This is referred to as the escape velocity. This is the speed that an object must reach in order to overcome the gravitational pull of the planet to make it into space.
What is the white planet-like object that rotates around the earth in space?
The moon.
What is a six letter word for a object in space that orbits a star?
Satellite
What is a large space object which revolves around a star called?
A large space object which revolves around a star is called a planet. The word planet comes from the Greek word, "aster planets" which means "wandering star".
Can an object have zero weight?
Yes, weight depends on the gravity of the planet. The weight of an object is different on a planet with a different gravity. An object has zero weight in outer space. No! An object does not have zero weight in outer space. Why? Because gravity exists in outer space.
