    Terminology:
            
    delta:      Distance between asteroid and earth in AU
    radius:     Distance between asteroid and sun in AU
    magn:       Magnitude (brightness) estimate    
    elong:      Elongation in degrees (angle sun-earth-asteroid)    
    AU:         Astronomical Unit (mean distance between earth and sun: 149597870.7 km    
    Perihelion: On this date the comet (or other type of body) is closest to the sun
