Eccentricity of escape velocity
WebThe escape velocity at the surface v 0 = 60 km/s. Plugging in v 1= 10 km/s I nd an eccentricity of e= 1:06 and a maximum grazing de ection angle of about 141 degrees. Problem 2. Impulse approximation and velocity kick due to a passing planet Consider a particle in a planetary ring with semi-major axis athat is in a circular orbit about a planet. WebOct 8, 2024 · The key difference is the shape of the orbit. For circular orbits the higher the orbit the slower the velocity, but an escape orbit is hyperbolic, not circular. Even though a higher circular orbit is slower if you want to transition from one circular orbit to a higher circular orbit you still need to increase your speed.
