Solar system

The asteroid, named 488453 (1994 XD), is due to pass the Earth at a speed of around 48,000 mph.

A new asteroid has been discovered orbiting the Earth, interacting only weakly with the planet in a way that classifies the object as a "quasi-moon".

Three of the asteroids are due to fly by our home planet at distances of around 4 million miles, while one will approach nearly as close as the moon.

High-definition images of sunspots on the sun's surface show the dark spots dotted with tiny pinpricks of light called umbral dots.

The sunspot, named AR3310, is so large that viewers don't need magnification to see it.

A plume of solar protons spat out by the sun has accelerated towards the Earth, and were funneled down into the polar regions by our magnetic field.

The Eta Aquariid meteor shower is due to peak on May 6 as the Earth passed through the particles left behind by Halley's comet centuries ago.

The asteroid, which is called 2023 HV5, will fly past the Earth on Wednesday at around 10 times the speed of a bullet being fired.

The northern lights were spotted as far south as California due to a severe G4 geomagnetic storm pummeling Earth's atmosphere and magnetic field.

Mercury also has a tail that streams out behind it as it gets close to the sun, but is only visible with a special filter that shows the glow of sodium.

The solar eclipse will appear as an annular eclipse for portions of the moon shadow's journey, and a total eclipse at others, due to the curvature of the Earth.

Rogue planets that float freely through space without a star to orbit are very difficult for astronomers to detect.

The eruption from Comet 29P/Schwassmann-Wachmann was unique, as scientists had predicted it based on the comet's brightness.

The time-lapse video shows the asteroid, known as 2023 DZ2, zooming through space at a speed of more than 17,400 miles per hour over 1 million miles from Earth.

Samples collected from the asteroid could hold clues on the creation of the solar system.

A livestream will show the asteroid flying by Earth at slightly less than half the average distance between our planet and the moon.

Solar tornadoes can have wind speeds of up to around 310,000 miles per hour, as opposed to the 300 mph top speed of tornadoes on Earth.

The asteroid, known as 2023 EY, was only discovered two days ago by a telescope at the Sutherland Observing Station in South Africa.

The coronal mass ejection exploded out from the far side of the sun, appearing in the shape of butterfly wings, so won't hit the Earth.

A livestream will show the full moon rising above the legendary skyline of Rome, Italy, and its famous monuments

Solar Cycle 25 is defying expectations it would be as inactive as the previous cycle, as sunspot numbers are already reaching Solar Cycle 24's maximum levels.

The spectacular red lights in the sky were caused by a G3 geomagnetic storm interacting with Earth's atmosphere.

Comet C/2022 E3 (ZTF), which has already been observed with the naked eye, is zooming away from Earth, perhaps never to return.

Astrophotographers across the world have posted spectacular images of the rare green comet ZTF as it passed close to Earth on February 1.

The green comet ZTF has passed its closest point to Earth but will still be visible for the next few weeks as it heads out of the solar system.

The comet will reach its minimum distance from our planet on February 1.

asteroid 2023 BU made one of the closest approaches to Earth on record Thursday, zooming past our planet just over 2,000 miles above the surface.

The comet C/2022 E3 (ZTF) is set to make a close approach to Earth on February 1, 2023, when it will come within roughly 26 million miles of our planet.

It may already be possible to see comet C/2022 E3 (ZTF) with the naked eye from very dark locations.

An asteroid known as 2023 BU will make a very close approach to our planet though.
