Does it take 1 year to circle the Sun?

The Earth’s Annual Journey Around the Sun

The Earth’s journey around the Sun takes approximately 365 days, or one year. This orbital period, the time it takes our planet to complete a single revolution, defines what we experience as a year, shaping our seasons and calendar systems.

The Earth’s orbit is not perfectly circular but rather elliptical, meaning it is slightly oval-shaped. As a result, the distance between the Earth and the Sun varies throughout the year. When the Earth is closest to the Sun, it is at a point known as perihelion, which occurs around January 3rd. Conversely, when the Earth is furthest from the Sun, it is at aphelion, which occurs around July 4th.

The Earth’s axis of rotation is tilted by approximately 23.5 degrees relative to the plane of its orbit around the Sun. This tilt is responsible for the seasons on Earth. As the Earth orbits the Sun, different parts of the planet are tilted towards or away from the Sun, resulting in varying amounts of solar radiation being received.

When the Northern Hemisphere is tilted towards the Sun, it experiences summer, with longer days and shorter nights. Conversely, when the Northern Hemisphere is tilted away from the Sun, it experiences winter, with shorter days and longer nights. The Southern Hemisphere experiences the opposite seasons at the same time.

The Earth’s annual journey around the Sun is a complex and fascinating phenomenon that has a profound impact on our planet and its inhabitants. Understanding this journey helps us appreciate the intricate workings of our solar system and the place of our planet within it.
