The Near Earth Asteroid Rendezvous (NEAR), after traveling 2.1 billion kmkm, is meant to orbit the asteroid Eros at a height of about 15 kmkm. Eros is roughly 40km×km× 6km×km×6kmkm. Assume Eros has a density (mass/volume) of about 2.3×103kg/m32.3×103kg/m3.
Part A
What will be the period of NEAR as it orbits Eros?
What is the relative velocity and impact energy of the Earth and an asteroid on 10/8/2023 with:
a) a diameter of 25 meters, aphelion at the Earth and perihelion at Venus
b) a diameter of 1 km and perihelion at Earth and aphelion in the asteroid belt (2.5 AU)
The Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion.
Give your answer in km/s with one significant figure.
