Honestly, you are not looking hard enough... If you figure this out you will be a step ahead of everyone else on the Internet.
Try searching more vague... Do a search for how do I find the distance between cities... or what is the diameter of the Earth!
Good luck... hope this helps!

Distance to the Sun
The mean Earth-Sun distance is very important in astronomy. It is called 1 Astronomical Unit or 1 AU.
It is rather easy to determine distances within the Solar System if you measure them in AU's.
The planets move around the Sun in orbits.
The orbits are really ellipses, but for our purposes we can consider them to be circles.
Call the radius of the orbit a.
This is the distance from the planet to the Sun.
Let us measure a in AU.
Thus for the Earth, a = 1.
By observing the position of a planet in the sky over a period of months, we can determine the radius a of its orbit.
Here is an example.
This involves trigonometry, which is beyond the knowledge base assumed for this course.
But you can see that you could measure the distance to Venus this way by simpling measuring the angle shown in the sky, making a scale drawing on a piece of paper, and measuring the distance between the Sun and Venus on your paper.
Knowing the distance to Venus in AU, we could measure how big 1 AU is in km if we could measure the distance to Venus in km.
The most accurate way to do that is to bounce a radar signal off of Venus.
Radar is microwave electromagnetic radiation.
Therefore it travels at the speed of light, c = 3 x 108m/s.
We can measure the time t it takes the signal to get to Venus and back.
The distance it went (twice the distance from Earth to Venus) is c t.
Methods like this give 1 AU = 150 x 106 km.
Later, we will want to know distances to stars. Getting the distance from the Earth to the Sun right is the first step.

Saturn. It is 1.43 billion kilometers away from the sun.
The deepest place in any ocean, is in the Pacific, 11,033 m (36,198 ft) in the Marianas Trench(?) off Guam.
Proxima Centauri is the nearest star to earth
that's all...hope it helps some!

Head over to http://www.google.com and ask
1. depth of the pacific ocean in meters
2. distance to closest star to earth in kilometers
3. diameter of the earth in kilometers
4. distance from denver, co to kansas city, ks (or mo) in kilometers
5. distance from sun to saturn in kilometers
6.distance from earth to the sun in kilometers
7. distance from san fransisco, ca to new york, ny in kilometers

1.The greatest known depth is located in the Mindanao Trench (West Pacific) where the British ship Cook (1962) found 11,516 meters in depth exceeding Mount Everest's height by 2,660 meters."
