Mass is what causes an object to have gravity. Above a certain mass and radius, the self-gravity of the object overcomes the yield strength of even the strongest solid materials. The surface may still be irregular, but overburden pressure causes the rocks deep inside to deform until the planet has a stable spherical shape. For solid bodies, that occurs between 200km and 300km radius, depending on the density and strength of the materials. Dwarf planets, moons and asteroids with radii less than 200km may be more potato-shaped, but larger objects will always be round.

Why is Eris not considered the tenth planet in our solar system?
Eris is a "dwarf planet", and does not have enough gravity to make the surface round, or to clear other objects near to it.

What shape is Mars?
Overal the shape of the planet Mars is round. However, there is some indentations in the planet that make it a little distorted and not perfectly round.
What is the criteria used to determine an object is a planet?
The three criteria set by the IAU in Prague in 2006 are 1) that it is in Solar orbit; 2) it is in hydrostatic equilibrium (massive enough to have a round shape) and 3) has cleared its orbital neighborhood.

What determine the length of a year on a planet?
The length of time it takes to make a complete orbit around the sun.
What action occurs to determine a year?
the time taken by a planet to make one revolution around the sun.
How do you determine the direction of an object?
establish a point of reference (it will depend on the number of dimensions involved to determine the amount of numbers needed) and make all measurements from there.
What does the term day mean for a planet?
In general terms a day for a planet is the time taken for the planet to make on rotation on its own axis. Likewise a year for a planet is the time taken for the planet to make one orbit (rotation round) its primary star. Where a planet is tidally locked to its primary, the day length and the year length will be the same, such that the planet keeps one face permanently towards it primary (like the Moon does to the Earth).
Can a dwarf planet be round?
Yes, dwarf planets can be round. Like regular planets, dwarf planets are large enough for their own gravity to pull them into a nearly spherical shape, making them round. Examples of round dwarf planets include Pluto and Eris.
How do you make your own planet on Littlebigplanet?
How you make your own planet is go to your campaign planet and go to the right. The planet with the holes on it is how you make your planet.
How do you make a model of planet earth?
That depends what exactly you want to model; what you want to use the model for. In the simplest case, you can take a ball, an orange, or some other round object, and say "This represents planet Earth".
