Write a functional programme in python:

Orbits of one body around another, such as a planet around the Sun, need not be circular. In general, they take the form of an ellipse. If you are given the distance of closest approach, 11, the perihelion, of the orbiting body and its linear velocity v1 at that point, then any other property of the orbit can be calculated from these two. Write a function 'orbit)' that takes two input values in the order perihelion distance and velocity and calculates the following numbers o Ellipse semi-major axis a o semi-minor axis b o orbital period T and o orbital eccentricity e Test your function (not on moodle) by confirming that the orbital period of Earth is one year (perihelion distance:1.471 x 1011 m, v1 3.0287 x 104 ms-1, G 6.67 x 10-11 m3kg1s2 and the Sun's mass is M 1.9891 x 1030 kg) The speed at the most distant point of the orbit is the smaller root of the quadratic equation 2GM 2GM 01 1 Get /2 from l2-l1v1/v2 For the remaining terms the formulae are a ( 12) 2 7T a b 0 /2+1 Return the tuple with values for a, b, T and e (in that order, in SI units)
