Mars and Earth are quite different. Compared to Earth, a year on Mars lasts almost twice as long – 686.98 Earth days. This is due to the fact that Mars is significantly farther from the Sun and its orbital period (the time it takes to orbit the Sun) is significantly greater than that...

In theory, the closest that Earth and Mars would approach each other would be when Mars is at its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). This would put the planets only 33.9 million miles (54.6 million kilometers) apart. However, this has never h...

Mars, after all, is the planet that most closely resembles Earth— that is, if Earth had an average temperature of minus 81 degrees Fahrenheit (minus 63 degrees Celsius), was ostensibly lifeless and had a thin Martian atmosphere [source: Mars Exploration]. Still, its geologic patterns resemble...
Traveling to the moon is no easy feat. Our natural satellite orbits Earth at an average distance of 238,855 miles (384,400 kilometers). So how long does it take to reach our closest neighbor from the moment a spaceship lifts off? Based on lunar missions from the past few decades, the...
To break it down simply, a day on the Moon lasts as long as 29.5 Earth days. In other words, if you were standing on the surface of the Moon, it would take 29.5 days for the Sun to move all the way across the sky and return to its original position again. However, as with all...
Life on Mars will be better in many ways.3.It is possible for us to live in a large building with many bedrooms. Robots will do most of the work, so we will have more time for hobbies.4.Every student can study, do their homework on computers and take exams online. Each student ...
