A credible web site says there are about 2,666 operational satellites orbiting Earth. This article says 1,900. Who's right? — Preceding unsigned comment added by 71.163.124.210 (talk) 19:07, 31 July 2020 (UTC)Reply

"In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon."

These two sentences contradict each other, or at least semantically very much not clear what satellite is, only artificially orbited objects are satellites or what. 91.82.182.182 (talk) 22:05, 19 January 2022 (UTC)Reply

"In the context of spaceflight" part removes the contradiction. In the context of spaceflight, the term "satellite" is synonymous with "artificial satellite," and need not have the "artificial" qualifier. --OuroborosCobra (talk) 23:06, 19 January 2022 (UTC)Reply

Then I propose the opening sentence to be a generic definition, not specific use cases. 91.82.182.182 (talk) 13:46, 20 January 2022 (UTC)Reply

OTOH the Satellite disambiguation starts with "A satellite is an artificial object which has been intentionally placed into orbit, such as:" so I don't even know anymore. It's murky, and needs some rewording for sure, but I don't know how. 91.82.182.182 (talk) 13:47, 20 January 2022 (UTC)Reply

Satellite is a general term and does not mean artificial satellite. There are artificial satellites and natural satellites. Lajoswinkler (talk) 20:19, 1 February 2025 (UTC)Reply
