Actually it isn't, it is shaped like an oblate spheroid, and for the same reasons that a water droplet is that the same shape, gravity physical forces and surface tension on a very large scale.
Before you point out that isn't really telling you why materials behave in that way, no one actually knows the reasons why, they just know that when material condenses the forces are such that a sphere is created. You can see it with every material from water to molten metal.The forces between the molecules pull the molecules together in a spherical shape, distorted by gravity.

Because Gravity pulls equally in all directions. When the Earth was forming, it was entirely molten rock. And, since Gravity pulls equally in all directions, the Gravity of the Earth pulled the molten rock into a sphere.

### How big is the sun

Hello Izzy...posting in the Fixya automotive with a question about the sun is kinda unusual...lol..but here goes...

It is a lot bigger than your average passenger vehicle...

The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km).

Here are some more interesting Sun facts:

Thanks for the points.

### What is the size of earth

However, Earth is not quite a sphere. The planet's rotation causes it to bulge at the equator. Earth's equatorial diameter is 7,926 miles (12,756 kilometers), but from pole to pole, the diameter is 7,900 miles (12,720 km) - a difference of only 40 miles (64 km)

Hope this helps

### How much air is contained in a 17 diameter balloon?

It really depends on the shape of the balloon.
If we assume that an air balloon is a sphere, then the volume of the balloon is:

V = (4/3) * Pi * R^3

"R" is the radius of the balloon. The volume might be a bit bigger if it has any bulges on it.

If we assume the balloon is a cylinder, then the volume is

V = L * Pi * R^2

"L" is the length and "R" is the radius of a circular cross-section.

### How do I determine the open space in a 12" cube

Determine the volume of the cube

Which is calculated by:
length x width x depth

then subtract the volume of the sphere's

Which is calculated by:
Number of spheres multiplied by (4/3) * pi * radius3

To figure out how many sphere's you can fit in the cube

Divide the width of the cube by the diameter of the sphere then cube that number
(try it with a larger diameter sphere for example 6" sphere and sketch it out, you will see why)

0.01" Sphere-Total Volume

12"/0.01"=1200

1200^3 = 1.728 E 9 = Number of sphere's in the cube

1.728 E 9 x (4/3) * pi * 0.0053=904.32 cubic inches

Volume of Cube = 1728

Remaining Volume = 1728-904.32 = 823.68

You should be able to figure out how to do the other one.

### Which layer of the sun is the hottest?and why?

Basic facts
• Central temperature: 15,000,000 K
• Surface temperature: 6,000 K
• Distance from Earth: 150,000,000 kilometers (1 Astronomical Unit)
• Size: 1,400,000 kilometer diameter
• Mass: 2 x 10 30 kilograms (300,000 x the Earth's mass)
• Average density: 1400 kg/m3(1.4 x water)
• Solar energy reaching Earth: 1400 Watts/m2 (solar constant)
• Total Luminosity of the Sun
• equivalent to the energy flow through a sphere surrounding the Sun
• The surface area of this sphere is 2.8 x 10 23 m2
• So, the total luminosity is:
• 1400 Watts/m2 x 2.8 x 10 23 m2
• = 4 x 10 26 Watts
