The orbit had a periapsis of 549.0 kilometres (341.1 mi), an apoapsis of 598.0 kilometres (371.6 mi), an inclination of 48.0° and an eccentricity of 0.00352, giving it a period of 96 minutes.

[3] The telescope's battery was accidentally overcharged and destroyed three days after the mission started.

When attempts to communicate with the satellite – while its solar panels were illuminated by sunlight – failed, the $20 million project was abandoned.

The eROSITA telescope was based on the design of the ABRIXAS observatory.

[5] eROSITA was launched on board the Spektr-RG space observatory on 13 July 2019 from Baikonur to be deployed at the second Lagrange point (L2).
