Why does the distance between Earth and Mars really between any two planets change during the year? Neither Earth or Mars' orbit is perfectly circular, so the distance between the two is constantly changing. Mars has a dense core at its center between 930 and 1,300 miles (1,500 to 2,100 kilometers) in radius. NASA Mars lander felt the ground shake during the impact while cameras aboard the Mars Reconnaissance Orbiter spotted the yawning new crater from space. Since 2003, this urban legend has been circulated through email and social media every time Mars makes a close approach. According to the Teacher's Guide to the Universe (opens in new tab) from Princeton University, the distance between Earth and Mars was first determined by Giovanni Cassini in 1672 using the parallax method. What is the farthest distance between Earth and Mars? Theyre launching spacecraft when Earth and Mars reach their closest point. According to NASA Goddard Space Flight Center's website, the ideal lineup for a launch to Mars would get you to the planet in roughly nine months. Though, the closest we've seen the two was 34.8 million miles in August 2003. Spaceships must also decelerate to enter orbit around a new planet to avoid overshooting it. xmlns:xsl='http://www.w3.org/1999/XSL/Transform'">. The astronomical unit (AU) is a light-year. Ten sample tubes, capturing an amazing variety of Martian geology, have been deposited on Mars surface so they could be studied on Earth in the future. When converted using the conversion factor 1 AU = 1.5 108 km, the distance between the planets is . Therefore, it would take about one and a half years to complete the elliptical orbit. This is another similarity with Earth, which has an axial tilt of 23.4 degrees. Then challenge them to identify all of the planets, outward from the sun (left to right): inner planets Mercury, Venus, Earth, Mars; outer planets Jupiter, Saturn, Uranus, Neptune, and Pluto.
