This document provides instructions for marking planet coordinates, finding halfway points in planetary orbits, determining circle equations and membership, and calculating distances between planets and from planets to the sun. Specifically, it instructs the user to: 1) mark planet coordinates and find halfway points in orbits; 2) determine the equation of a circle given its center and a point, and find values making a given point part of the circle; and 3) find distances of planets from the sun and between planets.
