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

Because mars takes longer to rotate all the way around so that the sun can reach all the areas of mars. This on mars takes longer than on earth because the earth doesn't take as long.

it will take 1.5 times longer for light from the sun to get to mars than to get to earth

It would be longer because Mars is further away from the sun and orbits slower than the Earth; therefore will take longer to complete a full revolution.

Because Mars rotates a little more slowly than the Earth.

A mars day is longer. Each Mars rotation takes 24 Earth hours and 39.5 Earth minutes. A mars day is about 25 hours long.

Astronomers refer to a planet's orbital period as its year. On that basis Mars does have a longer year than Earth.

No. A day on Mars is just a little bit longer than a day on Earth.

A day on Mars is slightly longer, about 24.62 Earth hours (24 hours, 37 minutes).

Since Mars is farther from the Sun, the length of its orbital path (an ellipse) is longer. Also, planets farther from the Sun don't have to move as quickly to maintain their orbits. Mars is only moving 81% as fast as the Earth.

A year on Mars is the same as 1.88 earth years. A day on Mars is slightly longer than a day on Earth.

It takes Earth about 365 Earth days to orbit the sun. It takes Mars about 687 Earth days to orbit the sun. This means it takes Mars about 1.88 times longer to orbit the sun than Earth.

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.

Mars takes about 686 Earth days (1.88 earth years) to revolve around the Sun. Because Mars is farther from the Sun, its orbit is longer, and it moves in that orbit at a slower speed than Earth.

A day on Mars lasts 24 Earth hours and 39.5 Earth minutes (24.6 hours). A year on Mars takes 687 Earth days.

One: It is farth out than mars. Two: It is larger and made of "Gas" so it takes longer than mars.

It takes a little longer than the earth.The earth takes 23 hours, and 56 minuteswhile it takes Mars 24 hours and 37 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 a little less than two Earth years.

Saturn is further from the sun than Mars. Which planet takes longer to orbit the Sun?

Longer. A day on Mars is around 39 minutes longer than a day on Earth, and it also takes Mars 668 days to make one trip around the sun (which means that seasons on Mars are also nearly twice as long as seasons on Earth are).

A day on Mars is just a little longer than a day on Earth. It takes Mars 24 hours and 37 minutes to rotate, whereas it takes the Earth only 23 hours and 56 minutes.

Mars takes just a little longer than earth does, at 24.6229 hours or 1.6 earth days
