The sine wave represents 360 degrees or a full circle. As the satellite revolves 360 degrees around the earth in its orbit this is how it is represented on a flat surface.
They are both geometric shapes. Both of the shapes has circles as their base.
A sphere, cylinder, cuboid, cone are examples of 3 dimensional shapes.

All orbits are ellipses. Some orbits, like the orbit of the Earth around the Sun, are almost (but not quite) circular. Other objects, like the Moon or Mars, have orbits that are more distinctly oval shaped.Comets have elliptical orbits with very high eccentricity; they are stretched so that they come quite close to the Sun, but still go dozens or hundreds of AU away. Some comets are less severely eccentric. Halley's Comet, for example, only goes out to about 30AU with a period of 76 years, while Comet Hale-Bopp has a period of closer to 2200 years.
They are physical characteristics of a plane shape. 3-dimensional shapes do have areas, but the concept of a perimeter is generally restricted to plane shapes.
Typically ellipses
Electrons generally orbit in ellipses.
Yes, there are different shapes and sizes of satellite dishes. You can find the best one for your home at www.montanasatellite.com/satellite_dish_covers.htm
ALL orbits are ellipses. Each and every one.
ellipses, parabolas, or hyperbolas. :)
Most cross orbits of planets which allows it to hit the planets easier. They do not go into a full orbit at all.
Kepler
Isaac Newton was his name.

If you are talking about the shapes of the planets themselves, then that would be a sphere. However, if you are talking about the shapes of their orbits, that would be an ellipse, which is a fancy term for an oval.
the moon appears to change shapes because you only see the part of it that reflects sunlight THAT YOU CAN SEE. so of the 1/2 of the moon that is illuminated, you only see part of it, the part changing as the moon orbits the earth.
All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
