The Martian atmosphere is also much lower compared to Earth. The pressure that its atmosphere generates on the planet surface is approximately 7.5 millibars. By comparison, the Earth's atmosphere exerts 1,000 millibars of pressure. However, a day on Mars is very similar in length to an Earth day, with a Martian day being approximately 24 hours and 37 minutes.
