The Extreme Ultraviolet Explorer (EUVE) was a NASA mission that operated in a near-circular, low Earth orbit. It was launched on June 7, 1992, and it was decommissioned on January 31, 2001.

Here are the key details of EUVE's orbit:

* Altitude: Approximately 550 kilometers (340 miles) above Earth

* Inclination: 28.5 degrees

* Period: Approximately 95 minutes

This orbit allowed EUVE to:

* Observe the entire sky over time due to Earth's rotation.

* Be relatively close to Earth for easier communication and data transmission.

* Minimize atmospheric drag which could have affected the spacecraft's stability.

The EUVE mission was a resounding success in providing valuable data on the extreme ultraviolet (EUV) radiation from various celestial objects. Its orbit played a critical role in enabling its observations and achieving its scientific goals.
