Bottom line: Halos around the sun or moon are caused by high, thin cirrus clouds drifting high above your head. Tiny ice crystals in Earth's atmosphere create the halos. They do it by refracting and reflecting the light. Lunar halos are signs that storms are nearby.

The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km).

Also known as a 22 degree halo or a sun halo, the ring is caused by sunlight passing through ice crystals in cirrus clouds within the Earth's atmosphere, the University of Illinois' Weather World Project 2010 explains. (See WW2010's website for diagrams that illustrate how it works.)

Sun pillar. A sun pillar is a halo phenomenon of a vertical shaft of light extending upward or downward from the sun. Typically seen during sunrise or sunset, sun pillars form when sunlight reflects off the surfaces of ice crystals associated with thin, high-level clouds (e.g.cirrostratus clouds).

Changes in the Earth's orbit At other times the ellipse is more pronounced so that the Earth moves closer and further away from the sun as it orbits. When the Earth is closer to the sun our climate is warmer. Circular orbit. Elliptical orbit – when the Earth is closer to the Sun, its climate is warmer.

A ring is a round band, usually of metal, worn as ornamental jewellery. The term "ring" by itself always denotes jewellery worn on the finger; when worn as an ornament elsewhere, the body part is specified within the term, e.g., earrings, neck rings, arm rings, and toe rings.

A limbal ring is a dark ring around the iris of the eye, where the sclera meets the cornea. It is a dark-colored manifestation of the corneal limbus resulting from optical properties of the region. ... Some contact lenses are colored to simulate limbal rings.

Vega has a radius of around 1.1 million mi / 1.8 million km, about 2.5 times bigger than our Sun. The mass has been estimated to be around 2.1 that of our Sun.

If you see a dark outline around your iris -- the colored part of your eye -- this is your limbal ring. It is darkest when we are at our healthiest and naturally fades with age and poor health.

The spring equinox, or vernal equinox, marks the beginning of the astronomical spring season and nearly equal hours of day and night. The day doesn't fall on the same exact date each year; rather, it can happen anytime between March 19 and 21 in the Northern Hemisphere.

Equinox and solstice are vital parts of the astronomical calendar which determine the transitions between the seasons. The equinox and solstice define the transitions between the seasons of the astronomical calendar and are a key part of the Earth's orbit around the Sun.

These bright circles of light around a light source are often referred to as “halos.” Halos around lights are most often noticed at nighttime or when you're in a dimly lit room. Halos can sometimes be a normal response to bright lights.

The sun has an interior consisting of the core, radiative zone, and convective zone. It has a visible surface called the photosphere, then the chromosphere, which usually isn't visible, and the very outer layer called the corona.

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.

If you're talking about majestic ice rings, like we see around Saturn, Uranus or Jupiter, then no, Earth doesn't have rings, and probably never did. ... In the case of Earth, it might have held onto a few ice particles that would have then orbited the planet, and eventually crashed through our atmosphere and burned up.
