The Sun and Other Stars Stars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages. Our Sun is an average-size star, maybe a little smaller than most stars. Stars the size of our Sun are known as Dwarf Stars.The largest stars can be 10 times larger across then the Sun. These are called Giant or SuperGiant stars.The very smallest stars are not much bigger than the planet Jupiter.tars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages.

The Sun - how far? how big? Distance to the Sun. The Sun is about 149 million km (93 million miles) from Earth. This is the average distance; since Earth's orbit is an ellipse, not a perfect circle, the Earth-Sun distance varies slightly throughout the year.

- The average distance (the mean distance) between the Earth and the Sun is about 150 million kilometers (93 million miles). The average distance from the Earth to the Sun is also called 1 astronomical unit (or AU).

- We average 310 days of sunshine each year. Average snowfall annually is a whopping 200+ inches with snow on ground from the end of October until middle of May. A typical summer day is sunny, in the 70s, and evening temperatures in the 40s. The humidity is very low and brief afternoon showers are not unexpected. A typical winter day is sunny and bright with highs averaging in the mid 30s and lows in the single digits.

Solar Energy The sun, an average star, is a fusion reactor that has been burning over 4 billion years. It provides enough energy in one minute to supply the world's energy needs for one year. In one day, it provides more energy than our current population would consume in 27 years. In fact, The amount of solar radiation striking the earth over a three-day period is equivalent to the energy stored in all fossil energy sources..

ABSOLUTE BEGINNERS Our Sun is classified as a yellow dwarf and is very much an average mid range star with a surface temperature of about 6000 C. Blue or even blue/green stars are very hot up to 50,000 C and are normally giant young stars which are very active or even hyper-active.ur Sun is classified as a yellow dwarf and is very much an average mid range star with a surface temperature of about 6000 C.

The Reasons for the Seasons Earth's orbit around the Sun is only slightly elliptical. The difference between its closest point to the Sun and its most distant is little more than 3 percent. That isn't enough to cause huge temperature swings. It translates to a difference of a few degrees Celsius on average.

Dexa scans: what they mean SPECIAL NOTE: Dexa scans are not the only kind of bone density test. If you want information about the other tests available go to: Bone density tests. Click here to read more about dexa scans and what the results mean: T scores, Z scores and more.exa Scans are used to measure bone mineral density because they: 1  are more accurate than regular X-rays. 2  A person would need to lose 20-30% of their bone density before it would show up on an X-ray. 3  require less radiation exposure than CAT scans or Radiographic Absorptiometry.

Why is our Sun classified as an âaverageâ star? Our sun is classified as average simply because of all the stars we can find in our galaxy the majority of them are very similar to our sun. In other words, on average most of the stars in the Milky Way are sun-like.Chug-a-Lug · 7 years ago. Thumbs up.eport Abuse.

VY Canis Majoris compared to Earth Temperature. Our sun is hotter than VY Canis Majoris, but that doesn’t make the star a nice place to spend the weekend. The average temperature on Earth, estimated by NASA, is 59 Fahrenheit or 15 celsius. VY’s estimated temperature is 4939 Fahrenheit (or 2726 Celsius).Y Canis Majoris is a mere 96,296 times bigger than Earth. I’d like to illustrate it, but Earth would be near to invisible on most comparisons. So therefore I’d like to use a more common picture that compared VY to our sun.

Average Annual Sunshine in American Cities The % Sun number measures the percentage of time between sunrise and sunset that sunshine reaches the ground. Total Hours is the average number of sunny hours the city normally has in a year. Clear Days is the average number of days annually when cloud covers at most 30 percent of the sky during daylight hours. Hours of sunshine are the means calculated for 1961 to 1990. The other data are averages taken from years of weather watching.

- In our solar system, we tend to describe distances in terms of the Astronomical Unit (AU). The AU is defined as the average distance between the Earth and the Sun. It is approximately 150 million km (93 million miles). Mercury can be said to be about 1/3 of an AU from the Sun and Pluto averages about 40 AU from the Sun.

- The surface of the Sun has a temperature of about 5,800 Kelvin (about 5,500 degrees Celsius, or about 10,000 degrees Fahrenheit). At that temperature, most of the energy the Sun radiates is visible and near-infrared light.

- By measuring the light received from the Sun we know that its radiation corresponds to a surface temperature of about 6000°C (or 6300 K where K is the symbol for units of Kelvin see the Units Glossary for more about the Kelvin scale). The organisms on Earth have long adapted to the nature of this sunlight.

Earth Rotation & Revolution around a moving Sun Earth orbits the Sun at an average distance of about 150 million kilometers every 365.2564 mean solar days, or one sidereal year. This gives an apparent movement of the Sun eastward with respect to the stars at a rate of about 1°/day, which is one apparent Sun or Moon diameter every 12 hours.
