In his new theory Copernicus was able to explain retro-grade motion in the planets without the use of large epicycles. With the Earth now out in the third orbit he was able to explain retro-grade motion as a perspective shift due to the motion of the Earth. As the earth passes the outer planets on its inner orbit the planets seem to move west even though they continue to move east in their orbits. The inner planets also seem to back up to the west as they pass Earth in their orbit closer to

Halley’s Comet Astronomers first observed Halley’s Comet as far back as 200 BCE. The comet ’s periodicity was first determined in 1705 by English astronomer Edmond Halley‚ who it was eventually named after. Halley ’s Comet last appeared in the inner Solar System in 1986 and won’t appear again until mid-2061. Although the nucleus of the comet itself is not that large‚ the coma can extend to a very large size. As the gas molecules in the coma are ionized by the solar ultraviolet radiation pressure

Of the many objects that orbit the Sun‚ most of the mass is contained within eight relatively solitary planets whose orbits are almost circular and lie within a nearly flat disc called the ecliptic plane.
