Nowadays, with several spacecraft orbiting or roaming along the surface of the Red Planet, scientists can use the speed of light to determine how far away Mars is from Earth, by measuring the time it takes for signals to reach Martian spacecraft, according to Universe Today (opens in new tab). Engineers must calculate the ideal orbits for sending a spacecraft from Earth to Mars. The orbits of Mars and Earth are also slightly tilted with respect to each other. From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the Sun. 2021 LPI Summer Intern Program in Planetary Science. "In the nine months it takes to get to Mars, Mars moves a considerable distance around in its orbit, about three-eighths of the way around the sun. Join our Space Forums to keep talking space on the latest missions, night sky and more! However, in 50 million years when Phobos crashes into Mars or breaks apart, it could create a dusty ring around the Red Planet. Big numbers and really not even all that big in an astronomical sense. Furthermore, you want a situation where Earth is at aphelion, at its most distant point from the Sun, and Mars is at perihelion, the closest point to the Sun. During opposition, Mars and the sun are on directly opposite sides of Earth. When Earth and Mars reach their closest point, this is known as opposition. They used the parallax method to calculate the distance to Mars with surprising accuracy. Due to their orbital mechanics, the closest approach can occur a few days before or after opposition depending on whether Mars is moving away from the Earth and sun or towards the Earth and sun respectively, according to Celestron (opens in new tab). The solar system includeseverything that isgravitationally drawnintothe sun'sorbit. For this reason, to calculate the distance, we use the average to measure how far planets are from one another. The minimum distance from the Earth to Mars is about 54.6 million kilometers. However, this has never happened in recorded history.
