WebThe Perihelion Point. The Earth reached its Perihelion this year on January 4, 2024, at 1:52 am EST (0652 GMT). At this point, the Earth was about 3 million miles (5 million kilometers) closer to the sun. However, the weather on Earth is not affected due to the Perihelion as the seasons are affected due to the tilt of the planet’s axis. Earth's perihelion takes place in early January. The exact date shifts because the calendar year doesn't perfectly match Earth's orbit. In 2024, perihelion will occur on Jan. 4, according to Time and Date(opens in new tab).
