The most noteworthy point found on Earth is Mount Everest which achieves a stature of 8.8 km.


The most minimal point on Earth is called Challenger Deep and at 10.9 km beneath ocean level, it is more remote than the pinnacle of Mount Everest.

Earth has a standout amongst the most roundabout circles of all the eight planets. Its pivot of turn is tilted 23.4° far from the opposite of its orbital plane, which delivers the seasons we encounter.

A year on Earth endures a little more than 365 days. It is really 1/4 of a day more than 365 days which is the reason we have a jump year at regular intervals.
