There are many issues associated with introducing this many satellites into orbit, from the dangers of space junk to obstructing our view of the night sky. The White House has given the Commerce Department authority to regulate satellites and space debris, but some members of Congress think that power should go to the Federal Aviation Administration. Some of these satellites are separated from each other by as little as 0.1° longitude. Answer (1 of 16): The lowest altitude at which air resistance is low enough to permit a single complete, unpowered orbit is about 125 km (80 miles). Musk's satellites would bring the number of satellites around Earth to a state astronomers . The constellation has grown to over 1,700 satellites through 2021, and will eventually consist of many thousands of mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers.While the technical possibility of satellite . However, a satellite needs to be going fast — at least 8 km (5 miles). Two medium Earth orbits are notable: the semi-synchronous orbit and the Molniya orbit. The Goddard Space Flight Center's lists 2,271 satellites currently in orbit. It took over 1,000 hours of extra-vehicular activity to piece together the station's 159 separate components. Selected satellites are colored red. In-The-Sky.org. As highlighted in the chart above, The Union of Concerned Scientists (UCS), determined that 2,666 operational satellites circled the globe in April of 2020.
