How many planets found in the solar system in 1850?

Why are planets that orbit around the Sun and satellites that orbit around these planets always called ellipses rather than perfect circles?
The planets, and the satellites that orbit around them, are affected by gravity from the sun and other celestial objects. The effects of gravity at different locations during their orbits prevent their orbits from being circular, and they become elliptical (more or less egg-shapped).

What sciencetist thought atoms was insivsiable?
The Earth is flat. If you get too close to the edge, you will fall off!The Earth is the center of the universe. The Sun and planets revolve around it!The above statements were early scientific theories that turned out to be false. The Earth is not flat; it is round. The Sun is the center of the universe and the planets revolve around it. As technology improved, new discoveries were made and old hypotheses were revised. During the 19th century, scientists including Dalton believed that the atom was indivisible. Scientists later discovered that this also was untrue.
