The comet Hale-Bopp has an elliptical orbit with the sun at one focus and has an eccentricity of e ≈ 0.995. The length of the major axis of the orbit is approximately 500 astronomical units. (a) Find the length of its minor axis. (b) Find a polar equation for the orbit. (c) Find the perihelion and aphelion distances.
Consider a spherical asteroid with radius 28.2 km and mass of 5.69 x 1018 kg. The acceleration due to gravity at the surface of the asteroid is ?
Possibly useful:
Fg=Gm1m2/r2
G=6.67 x 10-11 Nm2/kg2
Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 3.1x10^4 m/s when at a distance of 2.7x10^11 m from the center of the sun, what is its speed when at a distance of 4.7x10^10 m? Mass of the Sun is 1.99×10^30 kg. Gravitational constant is G=6.67×10^(−11) m^3 /(kg⋅s).
What is the formula?
