Consequently, one year on Mars lasts almost twice as long as on Earth, which is 680 6.71 Earth days and translates to 2,668.599 Martian days. Variation in seasons on Mars takes almost twice as long compared to the seasons on Earth, due to the distance of the planet from the sun. Mars has some similarities with the planet Earth having a tilt of 25.19 degrees compared to Earth, which is tilted at 23.4 degrees. One day on the planet Mars is nearly equivalent to a single day on Earth which takes 24 hrs, 37mins and 22 secs to spin once on its axis, and this implies that a single day on Mars is the same as 1.025957 Earth days (25 hours). Our planet Earth takes 365.256 days to go around the sun. On Earth, a cycle of a one day and night is 24 hrs. On the other hand, it takes an average of 24 hours for one solar day on Earth, and it means that this is the duration it takes the sun to show up again in the same position in the skies. One year on the planet takes as long as 1.92 days of the planet Venus.Įarth rotates once on its axis in exactly 23 hrs 56 mins and 4.1 secs. Therefore one year in Venus translate to about 224.70 Earth days and during this time the planet experiences only two sunrises and two sunsets. Just like Mercury, the slow rotation and the orbital speed of Venus imply that one solar day or the time taken for the sun to appear in the same location in the sky is 117 days.
Venus takes 243.025 Earth days (5,832 hours) to turn once on its axis. The planet is a retrograde rotation planet, meaning that it is rotating in the opposite direction of its path it takes around the sun. The rotational speed of Venus is 4.0 mph in comparison to the rotational velocity of the Earth, which is 1,040 mph. The planet is among the slowest in our solar system because all other planets have experienced flattening on both poles as a result of speeds of their spinning a characteristic which is lacking on Venus. Venus is the second planet after Mercury that is closer to the sun and lies in a distance of about 67.24 million miles away from the sun. A single year on the planet Mercury lasts about half as long as its day. The orbital time or the time the planet takes to go around the sun is 89.969 Earth days, implying that Mercury has a year which is equivalent to 88 days on Earth. It will take approximately 176 days for the planet to experience one sunrise to another sunrise. It takes Mercury approximately 58.64 Earth days (1,408 hours) to rotate on its axis, also known as the sidereal time. It takes about 175.97 Earth days from one sunrise to another, and this is due to the planet’s proximity to the sun and its high speed of orbiting around the sun. Mercury is about 35.98 million miles from the sun.
The planets Saturn and Jupiter are the largest, and they are gas planets which are made up of helium and hydrogen, while Neptune and Uranus are the outermost planets, and they are made up of volatiles such as methane ammonia and water. On the other side, there are terrestrial planets which are made up mainly of metals and solid rocks, and they are the four outer planets also known as giant planets which include Jupiter, Saturn, Uranus, and Neptune. There are four planets categorized as inner planets: Mercury, Venus, Earth, and Mars, and they are among the smallest. There are also five planets identified as dwarf planets and other smaller solar objects which together also orbit around the sun. Our solar system is made up of eight planets that orbit around the sun.
