||Named after Songoku's cloud (‹Ø“l‰_; kinto'un)
||Original name: Hephaistos (MPC 23959)
Perihelion: 0.359 AU (Mercury is .387)
Apihelion: 3.972 AU (Mars is 1.516, asteroids 2.365-2.795, Jupiter is 5.204)
X from earth's orbit at earth's orbit: 0.124 AU

|Apollo asteroids are asteroids which cross Earth's orbit and have a period longer than 1 year. They have semi-major axes greater than 1 astronomical unit (AU), and perihelion distances less than 1.017 AU.
Why would it be used?
1. Solar observatory
2. Slow transport
3. Ultra-high energy processing
4. Orbital control
5. Rescue station
Info from: Bill Owen of JPL:
It's asteroid number 2212, and according to JPL's Horizons service (http://ssd.jpl.nasa.gov) its orbital period is 3.18702 years and its spectral type is SG, which would make it (I think) mostly silicate.
