Where on Earth Is east not clearly defined?
At almost any point on Earth the four directions—north south east and west—are well defined despite the fact that our planet is round rather that flat. The only exceptions are exactly at the North and South Poles where the directions east and west are ambiguous (because points exactly at the poles do not turn).

When a planet in its orbit is closer to the sun it?
A planet’s orbital speed changes depending on how far it is from the Sun. The closer a planet is to the Sun the stronger the Sun’s gravitational pull on it and the faster the planet moves. The farther it is from the Sun the weaker the Sun’s gravitational pull and the slower it moves in its orbit.
