Tomorrow, January 3, 2026, at 12:15 p.m. EST (1715 UTC), Earth will reach perihelion, its shortest distance from the Sun along its elliptical orbit.

Earth will be 5 million km closer to the Sun compared to that at aphelion in early July. It will also be traveling faster by 3,600 km/h compared to its speed at aphelion.

The effect on temperature on Earth is minor due to this effect compared that of Earth's axial tilt, but it will heighten tides.
