the distance between earth and mars

And while here on Earth the seasons are evenly spread over the year, lasting 3 months (or one quarter of a year), on Mars the seasons vary in length because of Mars' elliptical, egg-shaped orbit around the Sun. On average, the distance between Mars and Earth is about 140 million miles (225 million kilometres). Mars remains visible in the weeks following close approach, but becomes fainter as Mars and Earth travel farther away from each other in their orbits around the Sun. While there are many star systems, including at least 200 billion other starsin our galaxy, there is only one solar system. The Mars landers seismometer has picked up vibrations from four separate impacts in the past two years. From this distance, it takes sunlight 13 minutes to travel from the Sun to Mars. It's only larger than Mercury, which has a diameter of about 3,032 miles, per NASA. The minimum distance from the Earth to Mars is about 54.6 million kilometers. A year on Mars lasts 669.6 sols, which is the same as 687 Earth days. That's about the exact same distance it'll be from Earth when the planets have another close approach in 2022. However, in 50 million years when Phobos crashes into Mars or breaks apart, it could create a dusty ring around the Red Planet. Close approach provides a launch opportunity window for missions to Mars. Mars is the second closest planet to Earth after Venus, yet it is still very far away. In the above number there are significant digits before the decimal point. Sometimes theyre at the closest point to the Sun (called perihelion), and other times theyre at the furthest point from the Sun (known as aphelion). Mars reaches opposition when there is a 180 difference between the geocentric longitudes of it and the Sun. Whether we're talking about science or science-fiction, there's something alluring about the red planet that has kept it in our collective imagination. Their launch dates are included for perspective. Its dry, rocky, and bitter cold. 1. Review planet order and relative sizes in our solar system.
