How far is Mars from Earth? Mars is less than 56 million km (35 million miles) from Earth at its closest approach, but it recedes to almost 400 million km (250 million miles) when the two planets are on opposite sides of the solar system.
Phobos, the innermost and larger moon, is heavily cratered, with deep grooves on its surface. It is slowly moving towards Mars and will crash into the planet or break apart in about 50 million years. Deimos is about half as big as Phobos and orbits two and a half times farther away from Mars.
NASA is keeping its eyes on human exploration of Mars. Our sustainable Moon to Mars exploration approach is reusable and repeatable – we will build an open exploration architecture in lunar orbit with as many capabilities that can be replicated as possible for missions to the Red Planet.
The Moon likely formed after a Mars-sized body collided with Earth several billion years ago. The resulting debris from both Earth and the impactor accumulated to form our natural satellite 239,000 miles (384,000 kilometers) away.
Mars - Red Planet, Orbit, Moons: Mars is the fourth planet out from the Sun. It moves around the Sun at a mean distance of 228 million km (140 million miles), or about 1.5 times the distance of Earth from the Sun.
Adding the Moon’s average distance from Earth, the farthest Mars could be from the Moon is roughly 401 million km + 384,400 km = 401.4 million km (approximately 249.2 million miles).
The Moon’s average distance from Earth is about 238,900 miles (384,400 km). However, this distance is not constant, as the Moon follows an elliptical orbit around Earth. When the Moon...
The farthest distance between Mars and the Earth equals 401 million km (249 million miles). The closest distance the two planets can get to each other is 54.6 million km (33.9 million miles). However, such a close approach never happened in recorded history.
India spent $74m on the Mars orbiter Mangalyaan and $75m on last year’s historic Chandrayaan-3 – less than the $100m spent on the sci-fi thriller Gravity. Nasa’s Maven orbiter had cost $582m ...
The Moon is an average of 238,855 miles (384,400 km) away. How far away is that? That’s 30 Earths. Average distance? Why mention the distance? Well, the Moon is not always the same distance away from Earth. The orbit is not a perfect circle. When the Moon is the farthest away, it’s 252,088 miles away. That’s almost 32 Earths.
