6 gru 2015 · While Earth takes precisely 23h 56m and 4 s to complete a single sidereal rotation (0.997 Earth days), Mars does the same in about 24 hours and 40 minutes. This means that one Martian day...
26 cze 2024 · Earth orbits the sun at a distance of 150 million kilometres and the sun orbits the centre of the Milky Way. Specifically, we are in the Orion arm, around 26,500 light years from the centre.
7 gru 2015 · Phobos measures about 22 km (14 mi) in diameter, and orbits Mars at a distance of 9,234.42 km when it is at periapsis (closest to Mars) and 9,517.58 km when it is at apoapsis (farthest).
16 maj 2023 · The average distance between Earth and Mars, as determined by NASA’s estimations, is roughly 225 million kilometers (140 million miles) or 1.52 astronomical units (AU).
29 lip 2023 · If you compare its diameter with Earth’s, Mars is almost half the size of our planet. When you compare both planets by volume, it turns out you could fit 6.5 Mars-sized planets on Earth. Mars’ small size could be the reason why its moons, Phobos and Deimos, are also quite small compared to our Moon.
4 mar 2014 · For planets, we have given minimum distances - the closest the planets come to Earth over the course of their orbits. Other distances (termination shock, heliopause) are uncertain and estimates...
9 kwi 2018 · Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth’s. The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth’s is rich in nitrogen and oxygen.
