ELFIN-A is a commercial and civil satellite operated by University of California (USA) for the purpose of space science.
Delivered via Delta 2 (launch vehicle) from Vandenberg AFB, it was launched into space on 15 September 2018 and orbits the Earth as a polar LEO satellite. ELFIN-A was constructed by University of California (USA).
ELFIN-A has a launch mass of 4 kg and orbits around the Earth with the COSPAR ID 2018-070E and NORAD ID 43617.
With an orbital eccentricity of 1.90E-03, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 443km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 469km. It takes 94 minutes to orbit the Earth at an inclination of 93 degrees to the equatorial plane of the Earth.
