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.
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?
the area in between Mars' and Jupiter's orbit to be ~1.6e18 km2. Since there are roughly 750,000 asteroids, how much area (in km2) is available for one asteroid? Use this calculation to argue whether you are likely (or not) to hit an asteroid while flying through the asteroid belt.
(Hint: To answer the first part of the question, find the area per asteroid)
