Astronomy on Mercury - Wikipedia
Due to the proximity of Mercury to the Sun, Mercury on average receives an energy flux from the Sun that is about 7 times the solar constant, but may reach nearly 11 times at maximum and about 4.5 times at minimum. The Sun will have an angular diameter of 1.733 to 1.142°.
Orbit and Rotation of Mercury - Planet Facts
It only takes 88 days for Mercury to orbit around the Sun at 47.8 km/sec (29.7 miles/sec). A typical year on Mercury would take 88 Earth days. Because of Mercury’s ever changing distance from the sun and its 3:2 spin-orbit resonance the temperature on Mercury’s surface is complex and varied.
