To better understand its formation, though, one first needs a more elaborate and detailed definition. Rings (or halos) around the sun are the refraction of the sunlight by millions of ice crystals present in cirrus clouds drifting at a height of 6000 meters (20 000 feet) or more above the earth's surface.
Solar halos or 22-degree halos are hazy rainbow-colored rings that occur at a radius of approximately 22 degrees around the sun. It results from the sun's light being refracted by ice crystals in Cirrus clouds in the upper troposphere at altitudes of approximately 6000 meters or 20 000 feet.
A Sun halo, a circle of light that creates a circle 22° wide around the Sun, is a related phenomenon. As with sundogs, hexagonal ice crystals suspended in cirrostratus clouds refract sunlight to create the halo, sometimes also called an icebow, nimbus, or gloriole.
But from every position you’re always able to see the deflected light from some of the crystals in the sky. And this is why you see the bright ring around the Sun. When you’re looking for halos, or rings around the Sun, make sure you always shield both eyes from the Sun.
These rings are caused by ice crystals within thin cirrus clouds, and there several different kinds of sun rings you can see depending on the weather conditions. One of the most common ones is called a 22° halo. They get this name because the ring is located 22 degrees away from the Sun itself.
The halos you see are caused by both refraction, or splitting of light, and also by reflection, or glints of light from these ice crystals. The crystals must be oriented and positioned just so with respect to your eye, for the halo to appear. That’s why, like rainbows, halos around the sun – or moon – are personal.

The sun is the closest star to Earth. That gives all Earthlings, especially astronomers, a front-row seat to its activities. One of the most striking features of the sun''s …
Filaments are cooler than the surrounding plasma, so they appear dark when viewed against the sun. When filaments are visible on the edge – or limb – of the sun, they are called prominences.
Have you ever looked up and spotted a large ring of light around the sun or moon? Scientists refer to these as 22-degree halos . They got that name because the radius …

The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.The …
A halo around the sun is caused by ice crystals in the atmosphere reflecting and refracting sunlight.
The Sun produces its energy at its centre via nuclear fusion reactions, where hydrogen nuclei are squeezed together to form helium nuclei. The Sun''s energy is transported to the surface and radiates equally in all directions. Our solar …
