Space weather probe Vigil will be the world's first space weather mission to be permanently positioned at Lagrange point 5, a ...

Using a space rock as a counterweight would, in theory, keep a giant parasol in place at a point 932,000 miles from Earth toward the sun.

Lagrange Points are unique positions in space where the gravitational forces of a two-body system, such as the Earth and the Sun, create regions of enhanced stability.

The spacecraft is planned to be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth.

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 ...

Dust launched from the moon’s surface or from a space station positioned between Earth and the sun could reduce enough solar radiation to mitigate the impacts of climate change.

Even as the Northern Hemisphere experiences winter’s chill, our planet on Tuesday, depending on your time zone, will be at perihelion, the closest it gets to the sun during its elliptical orbit.

FARGO — Earth will reach its closest point to the sun on Jan. 2, 2024, when the sun will be 91,403,034 miles away. The closest earth-sun distance is called perihelion, which is Greek for “near ...

Our planet whirls around the sun in an ellipse, rather than a circle. On Thursday the planet reached its farthest point from its star, known as aphelion.

The newly visible active regions join other current active regions facing Earth, NOAA 13190, 13191 and 13192, which span the sun's northern and southern hemispheres.
