The Sun

Jupiter's average distance from the sun is 483.5 million miles (778 million kilometers).

Sun plays a very important part for all the Living creatures in this world, if there were No Sun no creature could have existed, Plants grow due to sun light, they absorb sunlight and make their food, solar absorption panel are being currently widely used in many different parts of the world for electricity in which Panel Absorbs sunlight and generates electricity.

The beneficial effects of sun exposure are various, starting with the fact that it provides our body with vitamin D, without which we can come to bone diseases. But, at the same time, Sun can cause burns, wrinkles and can lead to skin cancer.

Besides vitamin D producing and syntheses, the Sun also prevents or helps curing some serious conditions such as: breast, prostate and colorectal cancer and multiple sclerosis.

When exposed to gentle sun rays the body is also protected against diabetes, ovary, bladder, womb and stomach cancer.

The sun releases post menstrual syndrome, or pains women encounter when they come to the monthly period.

It is interesting to notice that "the most fearful enemy" of skin - as it is considered to be the most common cause of skin cancer - can protect us from getting affected by skin cancer, psoriasis and skin tuberculosis when we expose regularly and progressively. On the contrary, we can develop melanoma when taking sudden sunbathes without preparing the skin previously.

Sun has also multiple beneficial effects on mood or affective disorders, such as stress, depression or anxiety and their symptoms: fatigue, insomnia, restlessness etc.

However, this does not mean that random exposure to the sun is allowed and risk-free, thereby a moderate exposure, especially in the morning and evening is recommended.

Most skin cancer is produced by UV (ultraviolet) rays that can cause two types of cancer: malignant melanoma, that most usually lead to death, and non-melanoma skin cancer, which is not that dangerous for our lives, but it is nevertheless slow-growing within our epidermis. The most likely to get skin cancer are the fair-skinned people that also get burned when over-exposing to the sun.

Melanoma is a cancerous (malignant) tumor which is produced by the cells in the skin that give its pigment, cells called melanocytes. Melanoma begins as a dark skin lesion and may spread rapidly to other areas on the skin and within the body.

The World Health Organization (WHO) also warns on their official web page against other diseases that may be caused by inadequate over-exposure to the sun.

The negative effects may be harmful to our eyes and vision, leading to: photokeratitis (inflammation of the cornea), photoconjunctivitis (inflammation of the conjunctiva), pterygium (growth of the conjunctiva on the surface of the eye), cataracts (the main cause for blindness) etc.

Excess sunbathing may also lead to weakening our immune system and other disorders of the skin besides cancer: lupus vulgaris (tuberculosis of the skin), psoriasis or vitiligo (a discontinuous depigmentation of the skin.)

The sun has two types of period of rotation, the sidereal rotation period and the synodic rotation period. The sidereal rotation period is 24.47 days. The synodic rotation period is 26.24 days.

The heat from the sun is generated by nuclear fusion in its core, where hydrogen atoms are converted into helium. This heat is then radiated out into space in the form of sunlight, warming our planet and providing the energy that drives Earth's climate and weather systems.

Yes, the sun has an atmosphere called the solar atmosphere. It consists of three main layers: the photosphere, the chromosphere, and the corona. These layers play important roles in the sun's energy output and solar activity.

The sun is a star, not a physical object like a person or a building. It doesn't have a height like we think of in terms of physical objects. The sun is a massive ball of hot gas, and its size is measured in terms of its diameter, which is about 1.4 million kilometers.

The Sun isn't the brightest star, actually it's considered quite dim in relation to other stars.
It appears brightest as it is closer to earth. There are other stars, some bigger or smaller, brighter or duller, in the vastness of the universe outside our rather small collection of planets orbiting our sun.

The sun is a non-living thing since it's only composed of hydrogen, helium and a few other elements.

No. You'd melt. Yes, but you would melt. So who would want to? Radiation is high near the sun. Would that do you in before you melted? This is true. It would actually depend on a lot of factors, chiefly the particulars of your space craft but radiation would probably the first thing to be concerned about. So you would probably fry before you melted.

Sunspots appear dark in color because they are cooler than the surrounding areas on the Sun's surface, which are much hotter. The cooler temperature of sunspots is due to magnetic activity inhibiting the flow of heat from deeper within the Sun.

The sun appears to rise in the east because of the way the earth turns.

Approximately 1.3 million Jupiter-sized planets could fit inside the Sun.

The sun emits energy in the form of sunlight, which is a mix of electromagnetic radiation. This energy is essential for life on Earth, as it drives processes like photosynthesis in plants and generates wind and ocean currents. Solar panels can also convert sunlight into electricity for various human uses.

The light from the sun is about 8 minutes and 20 seconds old by the time it reaches Earth. This is because light travels at a speed of about 186,282 miles per second, which translates to a 93 million-mile journey from the sun to Earth taking approximately 8 minutes and 20 seconds.

The sun's heat and light originate primarily in the conversion of mass to energy through nuclear fusion processes; the larger fraction through the proton-proton chain where hydrogen fuses into helium, and a smaller fraction through the CNO cycle which also catalytically consumes hydrogen and produces helium.

Estimates say about 600 million tons of hydrogen get converted to helium every second.. at that rate, the sun will run out of hydrogen fuel in about 5 billion years.

Solar, radiant, luminous, celestial.

The sun is a star which means it has it's own light, so it's always daytime on or near the sun. Earth is a planet. Planets do not have their own light. They depend on stars to give them light, which is what the sun does for earth. === ===
No, it is always day on the Sun. When we have night on the Earth, that is because our side of the planet is facing away from the Sun, and not getting any light. If you were on the Sun, there's no way to stop getting light.
No its a giant ball of gas and fire other planets orbit. Not vice vera therefore it cant change or have seasons.

Solar quantities refer to measurements or characteristics associated with solar energy, such as solar radiation, solar insolation, solar irradiance, or solar intensity. These quantities are used to evaluate the amount of sunlight available for generating electricity through solar panels or for other solar applications.

Anything that rotates has an imaginary line that it appears to rotate around,

and that's what's called the "axis". Since the sun definitely rotates, there's an

imaginary line through it that it seems to rotate around, and it's completely

proper to refer to that imaginary line as the sun's axis.

Molecules, which are everywhere, make things, like hot coco for example, feel hot when it moves fast, but when it moves slowly, it makes things, like ice, colder. To get it straight, the faster the molecules go in an object, the hotter it is; the slower it moves in an object, the colder it feels. And since the sun is more than 1,000 degrees Fahrenheit, its molecules are going a 100,000+ plus mph.

A solar oven uses sunlight to heat up food inside a box with reflective walls and a clear lid. The sunlight enters through the lid and is trapped as heat energy, which cooks the food at high temperatures, similar to a conventional oven. Solar ovens are environmentally friendly and can be used in areas where electricity or gas is limited.

Yes, but just a very tiny amount. Hydrogen and Helium make up 98% of the Sun, and Oxygen is less than 1%.
