Phoenix

Carbonaceous Asteroid
This asteroid is emitting a weak, intermittent signal at a frequency of 1540 MHz. Radius: 71 km.

"During a scan of the Phoenix system asteroid field, you detected an odd energy reading that Tali determined was quarian in nature. She led a recon team into the asteroid field, where she discovered an abandoned freighter. The team could not determine why the ship was there, but they did find a Prothean data disc on board."

Trivia

 * The Phoenix system may be named for the phoenix, a mythical bird from Arabia that burns itself in a fire and is reincarnated from the ashes every 500 years.


 * The stellar mass is derived from Tuntau's Keplerian ratio, based on its orbital distance of "nearly 20 AU". That implies the 19-20 AU range and a mass of 1.7-1.8. A value of 1.7 was chosen because it better aligns with the "main sequence" chart.
