Satellite Tracking provides detailed real-time and pass predictions for Earth orbiting satellites. See A Satellite Tonight shows you where to look with Google Street View. Uphere.Space real time tracking and predictions. As soon as new satellites are launched this application begins tracking them.
Irregular moons are probably minor planets that have been captured from surrounding space. Most irregular moons are less than 10 kilometres (6.2 mi) in diameter. The earliest published discovery of a moon other than Earth's was by Galileo Galilei , who discovered the four Galilean moons orbiting Jupiter in 1610.

True color image of the Earth from space. This image is a composite image collected over 16 days by the MODIS sensor on NASA’s Terra satellite. NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019.
Model of a Galileo satellite. This is a list of past and present satellites of the Galileo navigation system. The fully operational constellation will nominally consist of 30 satellites in Medium Earth Orbit, with 24 active and 6 spares equally divided into 3 orbital planes in a Walker 24/3/1 configuration.

Space probes are satellites designed for robotic space exploration outside of Earth, and space stations are in essence crewed satellites. The first artificial satellite launched into the Earth's orbit was the Soviet Union's Sputnik 1, on October 4, 1957. As of December 31, 2022, there are 6,718 operational satellites in the Earth's orbit, of ...
