Is that bright object in the southeast sky a planet or satellite or star?
It's likely that what you see is the planet Venus - nicknamed both the morning and evening 'star'.
What makes a moon a moon is the fact that it is smaller than the object it is orbiting, and is orbiting the object (the planet) constantly. The definition of a moon is "a natural satellite revolving around a planet". Since a satellite is an object that orbits a bigger object, usually a planet, and is not a planet due to its small size, it is considered a moon and not another planet.
A satellite is an object that orbits around a planet or body in space. There are artificial satellites and natural satellites. An artificial satellite is an object, like a space station, that has been set into orbit around a planet by humans. A natural satellite naturally finds its way into close orbit around a planet, like the moon naturally orbits the Earth.
A satellite is in orbit of a planet, going round and round indefinitely, We put objects into orbit around our planet, and the moon is our only natural satellite. We have never sent any object to another planet with the object of sending it round and round the planet. What NASA HAS done, is to send PROBES to other planets to acquire scientific data - sometimes by deliberately crashing the probe into the planet.
It is not large enough and does not orbit the Sun, it orbits Earth. A planet orbits around the sun. A moon orbits around a planet. "To be classified as a planet, an object has to go around the Sun, and if it also goes around something else, it must be significantly larger than that secondary object. When, as in the case of the Moon, the other object (the Earth) is much larger, the object…
