They found the diameter of the Earth by measuring the angle of the Sun above the horizon at noon at two different places, Alexandria and Aswan. The 7 degree difference gave the Earth's circumference as 360/7 times the distance between those two cities.

Why is it important to show the location of the planets accurately?
It is very important to show the location of the planets accurately. This is so scientists can determine the positioning of other bodies such as asteroids, stars, etc.
What do scientists look for when they are trying to find planets around other stars?
The first discoveries of extra-solar planets were made by looking for a slight wobble in the motion of the star. In the last couple of years, scientists have been able to detect the change in the spectrum of a star as a planet passes in front of it, and be able to analyze the atmosphere of that planet.
What do scientists know about the outside planets?
They are gas planets

How can studying earth help scientists understand other planets?
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
