What is Earth's Specific Mechanical Energy in its orbit aroundthe Sun?
Here are some properties you may or may not need to solve thisquestion (you'll have to decide which of these will help you):
Earth's semi-major axis in its orbit around the sun, a = 149.6 x106 km
Earth's mass is 6 x 1024 kg
Earth's Gravitational Parameter, μEarth = 3.986 x 105 km3s-2
Sun's Gravitational Parameter, μSun = 1.327×1011 km3 s-2
Sun's mass is 2 x 1030 kg The units on your answer should be km2s-2.
Please provide just the value and not the units in youranswer.
