The moon for the tides.
The man-made ones for communications, weather forecasting, GPS, and spying on each other.
The US protects its satellites through a combination of tactics, including encryption to secure communication signals, maneuvering satellites to avoid collisions with space debris, and monitoring for potential threats from other countries or entities. Additionally, the US has protocols in place for tracking and responding to any unauthorized or potentially hostile actions towards its satellites.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
Communication satellites: these are used to transmit television, radio, telephone, and internet signals. Navigation satellites: like the GPS system, these help determine location and provide accurate time information. Weather satellites: used to monitor weather patterns and provide important data for weather forecasting.
Natural satellites, we only have one - the Moon - helps us by providing a bit of moonlight at night, and also plays a role in stabilising the Earth on its axis. Artificial satellites helps us with navigation, communication, weather forecasts, pictures of the Earth and surveying.
Perhaps one of the most important and controversial uses of satellites today is that of monitoring the Earth's environment. Many satellites study features on the ground, the behavior of the oceans, or the characteristics of the atmosphere. Satellites that observe the Earth to collect scientific data are usually referred to as "Earth observation satellites." Sometimes the interpretation of their data has been controversial because the interpretation is difficult and people have used the data to call for substantial changes in human behavior.
because they help us understand space more

Yes. Satellites are one of the most important tools in hurricane forecasting.

There are currently 30 healthy GPS satellites in orbit.
because Satellites can send pictures of the planets for us to explore ( Mentally not Physically )

There are a great number of satellites currently orbiting the Earth, and they are ALL important; at least, important enough to SOMEBODY to spend millions of dollars to launch each one.Depending on your interests, the "most important" satellites are probably the weather forecasting satellites, followed by the communications and GPS satellites.

Satellites provide us with many things from internet, to google maps just to name a few.
