Why do planets move faster than on another?
the galaxy has difrent kinds of mass arouund each planet depending on what planet you are speaking of, it might be because of mass of the planet or what size a revolution (size of a complete circle) it must make
Characteristics of planets?
The IAU came up in 2006 with three definitions for a planet: # It must orbit the Sun. # It must be large enough for gravity to mould it into a nearly spherical shape. # It must have cleared the neighbourhood around its orbit. The third definition excluded Pluto as a planet.
Why is it necessary to know the distance to a planet in order to determine the planet's mass?
There is something missing from the question. The planet must have a moon. The only way to measure the mass of a planet is by using data about a moon orbiting the planet or data about the path of a spacecraft passing or going into orbit around the planet. If you know the distance to a planet then you can work out the moon's distance from the planet. The planet's mass can then be found. It's a bit of trigonometry and Newton's version of Kepler's Third Law. So that's the reason that it is necessary to know the distance to the planet.
How much gravity does it take to keep planets in orbit?
A fair amount, though it depends on the distances of the planets and their masses. The important thing is that the gravity (and therefore mass) of the central sun must be much greater than that of the planets, other wise they would orbit each other (or the sun would orbit the planet if its mass was much greater).
How big does a planet have to be to be a planet?
To be considered a planet, an object must be massive enough to be rounded into a spheroid by its own mass but not massive enough to cause thermonuclear fusion. Additionally, a planet must be orbiting a star or what used to be a star, and it must not be part of a disk of similar objects, like a Kuiper belt object.
When was planet Pluto is called a dwarf planet?
In August of 2006, the IAU (International Astronomical Unit) declared the definition of a planet. In order to be a true planet, a planet must meet these three criteria.It must be an object which independently orbits the SunIt must have enough mass so that gravity pulls it into a roughly speroidal shapeIt must be large enough to "dominate" its orbit (ie. its mass must be much larger than anything else which crosses its orbitPluto does not meet all 3 criteria, therefore it is not a true planet, but a Dwarf Planet.
Why all planets are sphare?
The reason planets appear to be spherical is because gravity compresses the planet into a shape that most evenly distributes the gravitational force among the planet's mass. Therefore, it must become rounded, or spherical.
Which statement is about our solar system are false?
Pluto is a planet Pluto was a planet but NASA stated that pluto was not a planet but a dwarf planet. the requirements for becoming a planet Because Pluto is not large enough to "dominate" its orbit, it is not a planet. (Neptune is about 8000 times more massive than Pluto, so Neptune is a planet and Pluto is a dwarf planet.) It must be an object which independently orbits the Sun (this means moons can't be considered planets, since they orbit planets) It must have enough mass that its gravity pulls it into a roughly spheroidal shape It must be large enough to "dominate" its orbit (i.e. its mass must be much larger than anything else which crosses its orbit)

As uranus mass is large then why its gravity is low?
Apart from the mass, you must also consider the distance. In the case of the surface gravity, that would be the radius of the planet.
What 2 conditions must be present on a planet if it is to have an atmosphere?
enough mass to keep it in placesource to create the atmosphere gasses

How can one become a movie editor?
To become a movie editor you must go to college and learn mass communication and video production.

Why are meteoroids not considered dwarf planets?
Too small. (To be even a dwarf planet you must have sufficient mass to give yourself a spherical shape.)
