The Sun

The Sun is the star at the center of our solar system. It provides our planet with light, warmth, and energy.

What is the temperature of the outermost layer of the sun?

The temperature of the outermost layer of the sun, called the corona, can reach over one million degrees Celsius. This high temperature is due to the extreme heat generated by the sun's magnetic fields and energy release from nuclear fusion in the core.

How do you get rid of sun burn?

Put some tea on the sun burn so it keeps it from blistering and then put some aloe lotion on the sun burn and in a few days the sun burn should be gone.

Can your skin get sun-bleached?

No, human skin cannot get sun-bleached like hair or clothing. However, prolonged sun exposure can cause skin damage such as sunburn, premature aging, and an increased risk of skin cancer. It is important to protect your skin from the sun by using sunscreen, wearing protective clothing, and seeking shade when possible.

What kind of nuclear reactive occurs in the sun fusion or fission?

The nuclear reaction that occurs in the sun is fusion. This process involves the fusing of hydrogen atoms to form helium, releasing a large amount of energy in the form of light and heat. Fusion is the main source of energy for the sun and other stars.

How is the amount of sunshine in a day recorded?

The number of hours of sunshine in a day is recorded in an instrument called a Parheliometer. A solid glass ball focuses the Sun's rays on to a strip of card, moving along the as the Sun moves through the sky. The longer the marks, the longer the period of sunshine.

What is orbit of the sun?

The sun is in an enormous orbit around the center of the Milky Way galaxy. It is estimated that it takes between 225 and 250 million years for the sun to make one orbit, called a galactic year. We are traveling around the center of the galaxy at a rate of about 220 km/second, which is .073% of the speed of light.

Does the sun have carbon?

Yes, the sun can be expected to have some carbon. That carbon would have come from the same source as the carbon on the earth.

Our sun is not massive enough nor hot enough to nucleosynthesize carbon. That would require a red giant. See http://library.thinkquest.org/17940/texts/nucleosynthesis/nucleosynthesis.html for some more details.

What does the photosphere of the sun do?

It is thought of as the surface of the sun. it is the outermost region where the sun is still opaque. This is where the photons from nuclear fusion escape the sun and make the 8 minute journey to earth.

Is the sun tilted?

The Sun is not tilted in the way that some planets are; it rotates on its axis, but its axis is not significantly tilted relative to its orbit around the Milky Way galaxy. However, its axis is tilted slightly in relation to its orbit around the center of the galaxy.

Why do so many objects orbit the sun?

The sun orbits the centre of the Milky Way galaxy at an average velocity of 828,000 km/hr. Even at that rate it still takes us about 230 million years to make a complete orbit of the Milky Way.

As to why it circles the center of the galaxy, this is due to the mechanics of formation of the galaxy. Matter attracted to the center of the system tends not to fall directly towards the middle but to swirl in like the whirlpool in the bathtub drain

What are the types of orbits?

There are basically three types of orbits.

* Sun Synchronous Orbits * Polar Orbits * Geosynchronous Orbits There are variations on these types. Visit related link below.

Age of the Sun?

The Sun is middle aged it formed 4600 million (4,600,000,000) years ago and will shine for another 5400 million years.

How long does sunlight take to travel from the sun to earth?

The Earth is (on average) 93 million miles from the Sun, and light travels at 186,000 miles per second. It's a curious coincidence tha the math on this says that light travels from the Sun to the Earth in a nice, round, 500 seconds.

This is equal to 8 minutes 20 seconds.

How old are the sun and earth?

The exact figure depends on which experiments you choose to give the most credence to, but the general consensus is that they both appear to be somewhere between four and five billion years old.

Why is it dangerous to look directly at the sun?

Looking directly at the sun can cause permanent damage to your eyes. The sun emits harmful ultraviolet radiation that can burn your retinas, leading to vision loss or blindness. It is important to always use proper eye protection when viewing the sun.

How can solar storms affect the Earth?

Solar storms can disrupt satellites, power grids, and radio communications on Earth by interfering with their electronics and signals. They can also create beautiful auroras in the atmosphere and pose health risks to astronauts in space due to increased radiation levels. Additionally, solar storms can affect Earth's magnetic field, causing compasses to be temporarily inaccurate.

What is the suns wheather?

The sun does not have "weather" in the same way Earth does. The sun experiences phenomena like solar flares and sunspots, but these are not considered weather.

Is the sun getting heavier or lighter as time goes on explain why?

there are three well known processes that each involve an ongoing change in the mass of the sun.

the sun radiates heat, thus losing energy and thus losing mass. the rate of mass loss by this process can be calculated quite easily and accurately.

the sun blows off matter continuously but somewhat irregularly. this flow of material is known as the solar wind. in this way the sun loses mass.

the sun still collects infalling stray chunks of loose material called meteors and in this way increases in mass.

i do not know the relative sizes of these three processes.

Does the Sun have radioactive energy?

No, the Sun does not produce energy through radioactivity. The Sun's energy comes from nuclear fusion reactions in its core, where hydrogen atoms are fused into helium, releasing vast amounts of light and heat in the process.

What is another name for solar plexus?

Another name for the solar plexus is the celiac plexus or coeliac plexus.

What are Ranger ricks solar scramble answers?

I'm unable to provide specific answers to puzzles or games as they may vary. I recommend trying to solve the Solar Scramble challenge on your own or seeking help from a walkthrough or online forum for hints.

A solar flare is one kind of?

A solar flare is one kind of solar eruption that occurs on the sun's surface. It releases intense bursts of energy, light, and high-energy particles into space. Solar flares can impact Earth's ionosphere and disrupt communication and navigation systems.

What is the Photosphere on the sun?

The photosphere is the outermost layer of the Sun's atmosphere that emits visible light. It is the region where most of the sun's energy is radiated into space. The photosphere is the part of the Sun that we see as the visible surface.

How big is a sunspot?

Sunspots expand and contract as they move across the surface of the Sun and can be as large as 80,000 kilometers (50,000 mile) in diameter, making the larger ones visible from Earth without the aid of a telescope
