Stars
Stars are balls of luminous plasma, held together by gravity. They can be seen twinkling overhead from our planet each night. They are enjoyable to look at, but also have been used as navigation tools for centuries.

What is the diameter from Mercury to the sun?
*Because of its extremely slow rotation, Mercury has no appreciable equatorial bulge as found on other planets.
3,032.3 miles.
Ah, what a delightful question. The star you are describing sounds like it could be a beautiful B-type star. These stars are much hotter and brighter than our Sun, shining brilliantly in the night sky. Just imagine the stunning colors and energy they bring to the universe.
If you weighed 120 pounds on Earth you would weigh how many pounds on the sun?
. pounds on Earth.IF you weight 1 on Earth you would weight 27 on the Sun (Gravity is 27 times stronger).
So if on the Sun you weigh 3030.6 pounds, on the Earth you would weight 3030.6/27 = 112.24.. pounds.
What do the sun and a light bulb have in common?
They both give off heat and light (fluorescent bulbs give off considerably less heat than incandescent bulbs), and most of the heat is "wasted" in that it is not used for any productive purpose.
How many AU is alpha centauri from the earth?
Alpha Centauri is the closest star system to Earth, located approximately 4.37 light-years away. One light-year is equivalent to about 63,241 astronomical units (AU). Therefore, Alpha Centauri is approximately 276,771 AU away from Earth.
What color is the suns radiation zone?
The sun's radiation zone is located in the innermost part of the sun's interior, where energy is transported by electromagnetic radiation. This zone is typically described as opaque and dense, with temperatures reaching up to 7 million degrees Fahrenheit. While the sun's core is known to emit primarily gamma rays, X-rays, and ultraviolet radiation, the color of the radiation zone itself is not a distinct observable characteristic due to the extreme conditions within the sun's interior.
Which is brighter Sirius or Rigel?
Well, honey, Sirius takes the crown for being the brightest star in the night sky, shining like a diamond in the rough. Rigel may be a hotshot in its own right, but it can't outshine the sass and sparkle of Sirius. So, if you're looking for some celestial bling, Sirius is the way to go.
What is a sun umbrella called?
Well, honey, a sun umbrella is technically called a parasol. It's like a fancy way of saying "I want shade without looking like a peasant." So, next time you want to shield yourself from those UV rays in style, just grab yourself a parasol and strut your stuff.
What kinds of star forms a red giant?
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.
when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
No, all-stars are not the same. All-stars refer to the best performers or players in a specific group or category, such as sports or entertainment. Each group or category will have its own all-stars based on their individual accomplishments and skill level.
What are the stages of stars life cycle?
SIMPLE EXPLANATION:
Step 1: The dust and gas from a nebula group together.
Step 2: When this group is big enough, energy is created - this group starts to shine.
Step 3: Then it reaches the size of a star.
Step 4: This star becomes a Red Giant - about 500 or more times as big as the Sun now.
Step 5: When the Red Giant runs out of its energy, it explodes as a supernova.
Step 6: This supernova leaves behind a little (50 km across) and dens star - white dwarf.
Step 7: If the Red Giant weighed at least twice as much as our sun, this white dwarf turns into a neutron star and then into a black hole. This whole step occurs in less than a minute.
(Step 8: If a really huge and dens star gets sucked into a black hole, a quasar might have formed)
Note 1: The lifecycle of a star lasts about 10-15 billions of years.
Note 2: Step 8 only may never occur in the lifecycle.
Why might the sun have made ancient peoples apprehensive?
They thought that eclipses of the sun would cause disasters
How many suns can fit in Arcturus?
Oh, dude, Arcturus is a red giant star, like the cool grandpa of our Sun. It's so massive that you could fit over 1.6 billion suns inside it. So, yeah, it's basically playing in a whole different league.
Why are there no comets close to the Sun?
Comets are composed of volatile materials such as ice, dust, and rocky debris. When they come close to the Sun, the heat causes these materials to vaporize and form a glowing coma and tail. This process, known as outgassing, leads to the gradual disintegration of the comet. Therefore, comets tend to stay in the outer regions of the solar system where they can remain intact until they approach the Sun.
Which is biggest sun or moon or star?
The moon is tiny. The earth is about 3 times bigger across than the moon.
The sun is an average sized star. It's about 110 times bigger across than the earth. =
There are many stars smaller than the sun, and many stars bigger than the sun. The sun and all stars are bigger than the moon.
What is the closest star near to the sun?
Alpha-Centauri
Distance from Sun/Earth of alphaa-Centauri from the Earth is now reckoned at 4.396 light-years or 4.159×1013 km.)
It is the same stella type as our Sun.
What does 'At night a candle's brighter than the sun' mean?
The phrase "At night a candle's brighter than the sun" is likely a metaphorical statement emphasizing the relative brightness of a small source of light in the darkness compared to a much larger source of light in the daytime. It suggests that even a small amount of light can have a significant impact in dark or difficult situations. This metaphor can be interpreted as highlighting the power of hope, positivity, or resilience in challenging circumstances.
What is the nuclear process that is taking place IN the sun?
Well, friend, the sun's nuclear process is called nuclear fusion. It's like a beautiful dance where hydrogen atoms come together to form helium, releasing a lot of energy in the process. This energy is what warms us, gives us light, and makes life on Earth possible. Just imagine the sun as a big, glowing artist painting the sky with its light and warmth.
What are the names of the food items with the name sun in it?
Ah, what a delightful question! One food item with "sun" in its name is sun-dried tomatoes. These tomatoes are dried in the warm sun, intensifying their flavor. Another is sunflower seeds, which come from the beautiful sunflower plant and make a tasty and nutritious snack.
How many times larger is the sun than a star that has 0.1 solar radius?
The sun has a radius of approximately 696,340 kilometers, while a star with 0.1 solar radius would have a radius of 69,634 kilometers. To calculate how many times larger the sun is, we divide the sun's radius by the smaller star's radius: 696,340 km / 69,634 km = 10. Therefore, the sun is 10 times larger than a star with 0.1 solar radius.
Why do can drinks explode when left in sun?
Liquid can drinks have carbon dioxide dissolved in the liquid.
When any liquid heats up , it hold less gas in solution, think of boiling water; dissolved oxygen is being released'.
The carbon dioxide is released into the 'air space' in the can. Since there is no relief of space; increase in volume, until you pull the tab, the carbon dioxide gas pressure builds up, to a point were the metal can cannot hold the build up of pressure. Hence the can explodes!!!!
Which constellation is also called the Great Bear?
The Great Bear is more correctly known by its Latin name, 'Ursa Major'.
