Question:
Why does Halley's comet make an elliptical orbit around the Sun?
Why does the comet not fly into space?
Explain the type of gravitational field that controls this comet.
Replies:
The kind of gravity that attracts the comet to the Sun is exactly the sam e
as we experience here on Earth. The way we can know that is because the
orbit is so close to being an ellipse. Newton's discovery was that for
gravity the orbits of objects that cannot escape are either circles or
ellipses.
