A trip to Mars will be very complex. Point out the locations of the asteroid belt (between Mars and Jupiter) and Kuiper belt (past Pluto) if they were included in this illustration. Many Mars missions have taken advantage of the close distance to visit the Red Planet. 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. Both are close to essential to allow a planet to retain a human breathable atmosphere. It is a unit of length equal to the average distance from Earth to sun, approximately 149,600,000 kilometers (92,957,000 miles). It is also easier to see with telescopes or the naked eye. The closest recorded approach of the two planets occurred in 2003 when they were only 34.8 million miles (56 million km) apart. The 10 sample tubes being dropped on Mars surface so they can be studied on Earth in the future carry an amazing diversity of Red Planet geology. It is a unit of length equal to the average distance from Earth to sun, approximately 149,600,000 kilometers (92,957,000 miles). If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home. For example, stating that the planet Jupiter is 5.2 AU (5.2 Earth distances) from the sun and that Pluto is nearly 40 AU allows you to more easily compare the distances of all three bodies. To be exact, the distance between Mars and Earth is less than one light-year, which is 4.2105 light-years. Reaching the planet will be a feat on its own, as Mars is between 34-250 million miles away from Earth, depending on the planetary rotation around the sun. Mars is one of the easiest planets to spot in the night sky it looks like a bright red point of light. Sustainability Policy| According to NASA (opens in new tab), a one-way trip to Mars would take about nine months. The farthest apart they can be is about 401 million km. Instead, they're looking for signs of life that existed long ago, when Mars was warmer and covered with water. 23 and NASA's Mars 2020 mission launched from Florida's Space Coast on Jul. (Mercury) Which is the largest? New York, NASA Mars lander felt the ground shake during the impact while cameras aboard the Mars Reconnaissance Orbiter spotted the yawning new crater from space. To traverse that distance would likely take several months to years depending on how fast of a rocket you have. The Moon is 384,400 kilometers (km) (240,250 miles) from the Earth. Nearly all comets orbit the Sun in same direction and roughly the same plane. Even today, it is frequently called the "Red Planet" because iron minerals in the Martian dirt oxidize, or rust, causing the surface to look red. Alien conspiracy theory: Earth and Mars is the same planet; Humans, aka Mearthians, pretend it's two planets so they get more funding from the Galactic Union. Log in for more information. The Mars landers seismometer has picked up vibrations from four separate impacts in the past two years. Pluto, which used to be considered the ninth planet, is now classified as a dwarf planet and part of the Kuiper Belt. Mars and Earth are farthest apart when they are both at aphelion and on opposite sides of the sun. Today, water on Mars is found in the form of water-ice just under the surface in the polar regions as well as in briny (salty) water, which seasonally flows down some hillsides and crater walls. The average distance between Mars and the sun is 142 million miles (228 million kilometers). After such storms, it can be months before all of the dust settles. A year on Mars lasts for about 687 Earth days or 669 sols (Mars days). Feb 18, 2016 The distance depends on where Earth and Mars are in their respective orbits.
