Why do Mercury and Venus have shorter years than Earth?
Why do Mercury and Venus have shorter years than Earth?
Planets that orbit closer to the Sun than Earth have shorter years than Earth. Planets that orbit farther from the Sun than Earth have longer years than Earth. This happens for two main reasons. If a planet is close to the Sun, the distance it orbits around the Sun is fairly short.
How is a Mercury year shorter than a Mercury day?
It’s proximity to the Sun also means that it orbits the planet quite rapidly. To break it down, Mercury takes roughly 88 Earth days to complete a single orbit around the Sun. Between this rapid orbital period and its slow rotational period, a single year on Mercury is actually shorter than a single day!
Why is one year on Earth 365 days but on Mercury it is 88 days?
Due to the fact that Mercury is so close to the Sun, it only takes 88 days to orbit the Sun, much shorter than the 365 days it takes the Earth to orbit fully around the Sun!
Why does Mercury have the smallest orbit?
Because of its nearness to the Sun—its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets.

Why do we age slower on other planets?
It is the number of times the Earth has orbited the Sun since the day we were born. If we were to live on another planet in the Solar System our age would be different because each planet takes a different amount of time to orbit the Sun. In other words each planet has a different year length.
What planet has the shortest period?
The planet with the shortest orbital period (year) is Mercury. The innermost planet in our Solar System completes its eliptical orbit around the Sun once every 87 (Earth) days 21 hours.
How can Mercury’s day be longer than its year?
A quirk of Mercury is that each rotation doesn’t see the Sun rise and set. Mercury’s orbit is more squashed than other planets. This means it actually takes 176 days for the Sun to appear to rise and set. This makes a solar day on Mercury longer than its year!
Why does Mercury’s day last almost 59 Earth days?
Or in another way, Mercury’s day is really long. That’s because when a planet is so close, the Sun’s gravity exerts strong tidal forces on the near and far sides of the planet that have slowed Mercury’s spin way down. It takes about 59 Earth days for Mercury to complete just one rotation on its axis.
What happens to Mercury every 88 days?
Mercury speeds around the sun every 88 Earth days, traveling through space at nearly 112,000 mph (180,000 km/h), faster than any other planet. Its oval-shaped orbit is highly elliptical, taking Mercury as close as 29 million miles (47 million km) and as far as 43 million miles (70 million km) from the sun.
Why is a year not exactly 365 days?
It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
Which planet has 13 known moons?
Neptune has 13 known moons, though most are small and orbit closer to Neptune than its rings. Triton is Neptune’s only large moon with a diameter of 2,704 km, and Proteus and Nereid are Neptune’s second and third largest moons, respectively.
What makes Mercury so unique?
Mercury is the only metal on earth that is liquid at room temperature. Liquid mercury is so slippery that it will fall your skin if you try to hold it. It is so heavy that 2 tablespoons of mercury weighs about one pound!
Why does Mercury have the weakest gravity?
Since Mercury has less mass than Earth, the surface gravity on Mercury is less than the surface gravity on Earth. The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury.
What’s weird about Mercury’s orbit?
Mercury also has the most lopsided, out-of-round orbit of any planet in the solar system. Its Sun distance mutates from 28.5 to 43 million miles (46 to 69 million kilometers). This is huge because its solar intensity thereby varies from six to 14 times versus what we experience on Earth.
What is the secret of Mercury?
Mercury has a big iron core While scientists knew before that Mercury has an iron core, the sheer size of it surprised scientists. At 85%, the proportion of the core to the rest of the planet dwarfs its rocky solar system companions. Further, scientists measured Mercury’s gravity.
What is Mercury famous for?
Fastest Planet The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.

Why is the period of Venus shorter than the period of Earth?
Since Venus’ orbit is closer to the Sun than Earth’s, Venus has a shorter orbital period and “laps” Earth at regular intervals.
Why is a year on Venus shorter than a year on Earth?
It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun. That’s 243 Earth days to rotate once – the longest rotation of any planet in the Solar System – and only 224.7 Earth days to complete an orbit of the Sun.
Is Mercury’s year shorter than Earth’s year?
A year is the time it takes the earth to make one revolution – a little over 365 days. We all learn in grade school that the planets move at differing rates around the sun. While earth takes 365 days to make one circuit, the closest planet, Mercury, takes only 88 days.
Why is Venus day longer than Mercury?
The gravity of the larger body keeps the rotational period of the smaller body in sync with its orbit around the larger body.
