The Earth's orbit is influenced by the gravitational pull of the other planets in our solar system, particularly Jupiter and Venus. These gravitational forces cause the Earth's orbit to vary slightly over time, a phenomenon known as orbital precession. As a result, the timing of perihelion shifts by about 1 day every 72 years.
It may seem counterintuitive that the Earth is closest to the Sun in January, when it's winter in the Northern Hemisphere. The reason for this discrepancy lies in the tilt of the Earth's axis, which is approximately 23.5 degrees. As the Earth orbits the Sun, its axis remains tilted in the same direction, resulting in the changing seasons. when is earth closest to the sun
The Earth's orbit around the Sun is not a perfect circle, but rather an ellipse. This means that the distance between our planet and the Sun varies throughout the year. At its closest point, the Earth is about 91.5 million miles (147 million kilometers) away from the Sun, and at its farthest point, it is approximately 94.5 million miles (152 million kilometers) away. But when exactly is the Earth closest to the Sun? The Earth's orbit is influenced by the gravitational
