Why does a year on mars take longer than a year on earth?
Years on Mars are longer because a year defines how long a planet takes to orbit the sun, and Mars is farther from the sun so it takes longer to orbit the sun
It depends on where Earth and Mars are in their orbits. Since Mars takes longer to orbit the sun than Earth does the distance between the two planets varies considerably. When Earth and Mars are closest a beam of light will take about 4 minutes to reach Mars from Earth. When they are farthest (on opposite sides of the sun) a bean of light would take about 12 minutes.
If you mean unit of time, then yes. A second on Earth is the same as a second on Mars, as is a minute, or an hour. Mars' length of day, however is slightly longer than an average Earth day because it rotates slightly slower than the Earth. A Martian year is also longer than a year on Earth because its orbit around the Sun is longer. One orbit around the Sun for Mars takes…
No The time it takes for the Earth to rotate a full rotation is 24 hrs. However, the time it takes for Mars to rotate a full rotation is 24 hrs and 39 mins, which is 39 mins longer than the rotational period of the Earth. Comparing the rotational periods of Mars to the Earth, we figure out that Mars rotates slower, not faster, than the Earth.
Mercury, Venus, and Mars all have longer days, both solar and siderial (rotational) days. Each rotation of Mercury takes 58.65 Earth days, Venus takes 243 Earth days, and Mars takes 1.03 Earth days (24.6 hours). There could be exoplanets with a period of rotation longer than our day. The five dwarf planets (including Pluto) also have a longer rotation period than an Earth day.
