The Earth is picking up speed, and it’s forcing scientists and timekeepers to consider an unprecedented move. According to ...

Tuesday, July 22, is expected to be the second of three days in 2025 where more than a millisecond could be shaved off the ...

Throughout my research, I’ve found that Earth’s regular pattern of seasons is unique. The rotational axis that Earth spins on, along the North and South poles, isn’t quite aligned with the vertical ...

Thanks to atomic clocks (and all the worldly forces that influence them), scientists know that Earth's rotation has begun to ...

On July 3, 2025, at 3:54 pm ET, the Earth will officially reach its furthest point from the Sun for this year. This is called aphelion. Our planet’s orbit is very close to a circle, but it is not a ...

Earth's orbit around the Sun also plays a role in the changing of seasons. The orbit is not a perfect circle, but rather an elliptical shape. While this elliptical orbit does affect the distance ...

We now know that Earth orbits the sun elliptically and, at the same time, spins on an axis that is tilted relative to its plane of orbit. This means that different hemispheres are exposed to ...

Earth on Tuesday made its closest approach to the sun, an annual celestial event that happens to occur at the start of the new year. The planet follows an elliptical orbit around the sun, rather ...

NASA launches probe on historic mission to study the sun 02:38. On January 2, 2021, Earth is closer to the sun in its elliptical orbit than on any other day of the year, marking an annual event ...

Earth’s orbit around the Sun is not circular, but an ellipse. The perimeter of Earth’s orbit is roughly 584 million miles (940 million km). Skip to content.

Earth’s seasons result from a variety of factors, including orbit and axial tilt. When a planet has an obliquity of more than 54 degrees, that planet's equator grows icy and the pole becomes warm .
