Newton shone monochromatic light on his newly finished lenses which created light and dark rings by which he determined the precision of his homemade lenses. The application of these rings to light behavior did not arise until into the nineteenth century. The Newtonian telescope was the first telescope to use reflecting mirrors in stead of multiple lenses like Galileo's telescope. Mirrored telescopes enabled future scientists to record at wavelengths shorter than that of visible light. Laws of Motion Applied to Astronomy Newton's Laws changed astronomy by explaining the behavior of the planets orbiting the sun.
Any body orbits other bodies due to the effects of gravity.
Newton's laws enabled early astronomers to determine the mass of planets, the rate at which planets move, and the distance between them. Newton's laws remain to be an important tool to astronomers today. New technologies and great minds have taken Newton's Laws to the ends of the Earth and back.
