DAYS IN ONE YEAR ON EACH PLANET

1. Mercury – 88 Days

Mercury is the closest planet to the Sun and has the shortest year in the Solar System. It takes only 88 Earth days to complete one orbit around the Sun. Because Mercury is so close to the Sun, it travels at a very high speed of about 47 kilometers per second. The planet has a rocky surface filled with craters, similar to Earth’s Moon. Mercury has almost no atmosphere, causing extreme temperature changes between day and night. A year on Mercury is much shorter than on Earth, making it unique among the planets in our Solar System.

2. Venus – 225 Days

Venus is the second planet from the Sun and completes one orbit in 225 Earth days. Often called Earth’s twin because of its similar size, Venus is actually very different. It has a thick atmosphere composed mainly of carbon dioxide, creating a powerful greenhouse effect that makes it the hottest planet in the Solar System. Venus rotates very slowly and in the opposite direction of most planets. Its surface is covered with volcanic plains and mountains. Although a year on Venus is shorter than on Earth, the planet’s harsh conditions make it one of the most hostile worlds known.

3. Earth – 365 Days

Earth is the third planet from the Sun and takes approximately 365.25 days to complete one revolution around it. This period is called one year. Earth is the only known planet that supports life due to the presence of liquid water, a suitable atmosphere, and moderate temperatures. The planet’s yearly orbit creates the seasons because of Earth’s tilted axis. Earth has one natural satellite, the Moon, which influences tides and stabilizes the planet’s rotation. Its diverse ecosystems support millions of species. Earth serves as the standard by which the orbital periods of other planets are measured.

4. Mars – 687 Days

Mars is the fourth planet from the Sun and takes 687 Earth days, or about 1.9 Earth years, to complete one orbit. Known as the Red Planet, Mars gets its color from iron oxide, commonly called rust, on its surface. It has the largest volcano and one of the deepest canyons in the Solar System. Mars has a thin atmosphere composed mostly of carbon dioxide. Scientists study Mars extensively because it may have once contained liquid water and could potentially support future human exploration. Its longer year results from its greater distance from the Sun compared to Earth.

5. Jupiter – 4,333 Days
