Two objects - a satellite and a carrier rocket's upper stage - have ended up in orbit as a result of North Korea's launch of a carrier rocket on February 7, a spokesman for Russia's Space Surveillance Center said on Feb. 9.

"We are monitoring two objects. They are a satellite and an upper stage," he added.

When describing the parameters of the orbit of these two objects, the spokesman said that "their altitude is approximately 500 kilometers, with an inclination of 97 degrees."

The specialist also suggested that, judging by the orbit parameters, "it is most likely an Earth remote sensing satellite."

"We see it," he added.

The U.S. Space Surveillance Network reported earlier that North Korea's KMS-4 satellite was assigned the international identification number 2016-009A. It was put into a near-polar orbit with an inclination of 97 degrees, with an apogee altitude of 501 kilometers, and a perigee altitude of 465 kilometers, it said.

The upper stage of the Unha-3 carrier rocket, which has been assigned the international identification number 2016-009B, has remained in an orbit with similar parameters.

Both objects take approximately 94 minutes to complete one orbit of the earth.
