Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.
Orbital radius of the earth r = 1.5 × 1011 m. Given mass of the sun M =1.9 × 1030 kg. Using Kepler's third law to calculate the time-period T of earth's rotation in year.
Universal constant of gravity G = 6.67 × 10-11 Nm²/kg2.
In your own words, describe the meaning of Kepler's Third Law of Planetary Motion. Do not use any equations, do not describe the equations in words, just tell me the conceptual meaning.
