It takes Venus about 224.7 Earth days to orbit the Sun.
It takes 10,759 Earth days (or about 29½ years), to orbit once around the Sun.
The Moon does not orbit the Sun. It orbits the Earth.
Mercury takes 87.97 days to orbit the Sun, and there are 24 hours in a day.
If the satellite is anywhere near Earth's surface, it will take about one and a half hours to orbit Earth once. As the orbit gets higher, it will take longer - both because it must travel a longer distance, and because it will be slower.
There are many satellites that orbit the earth in a day or less. All of them are man made. The only real satellite that orbits the earth is the moon. That takes 28 days to complete a single orbit.
One year.
Most satellites in low Earth orbit rotate around the Earth approximately 15 times per day. This means they orbit the Earth about every 90 minutes.
It takes 365.24 days for the earth to complete its orbit around the sun, so one year. We have a leap year every four years to make up for the extra quarter day.
