What star means?
A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but due to their immense distance from Earth they appear as fixed points of light in the sky.
What is a sentence for star?
“We saw countless bright stars tonight.” “He studied nearby stars with his telescope.” “I was surprised to see a falling star.” “There were a few big movie stars at the party.”
What is a 5 star sentence?
A five star sentence has correct capital and lower case letters, is neatly written, has finger spaces between words, ends with punctuation, and uses interesting word choice.
What are stars answer in one sentence?
A star is a very large ball of bright glowing hot matter in space. That matter is called plasma. Stars are held together by gravity. They give out heat and light because they are very hot.
What is a metaphor for stars?
Everyone has seen stars in the night sky. Metaphorically a star is someone who is famous in his or her field, as in being a movie star, or a rising star in politics.
How many types of stars are there?
What are the 5 types of stars?
The Different Types of Stars
- Protostar. A protostar is what comes before a star has formed – a collection of gas that collapsed from a huge molecular cloud.
- T Tauri Stars.
- Main Sequence Stars.
- Red Giant Stars.
- White Dwarf Stars.
- Red Dwarf Stars.
- Neutron Stars.
- Supergiant Stars.
What is the rarest star type?

What is the rarest planet?
Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the center, and a third star swirling around its siblings from several hundred million miles away.
What color star is hottest?
What if our sun was a blue giant?
Red stars have temperature around 2000- 3000K and blue stars around 10000–20000K. So imagine if sun would be a blue star, it would be so hot that it would become nearly impossible for a planet at a distance as earth to sustain life.
Does Blue Sun exist?
What if we had a blue sun? Though the sun may appear yellow or reddish to the naked eye, it’s actually an ordinary white star. And the blue version released by NASA was made using a specific wavelength of ultraviolet light known as CaK, which is emitted by ionized calcium in the sun’s atmosphere.
Is a Blue Sun Real?
When the Sun is high in the sky, the shorter waves, primarily the blue, strike air molecues in the upper atmosphere and bounce around and scatter. Hence explaining why the sky looks blue. Some people think that enough blue light is scattered out in the Earth’s atmosphere to cause the Sun to appear slightly yellow.
What if our sun was a black hole?
Our Sun is too small a star to end its life as a black hole. But what would happen if the Sun were suddenly replaced with a black hole of the same mass? Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun.
Is our sun a black hole?
No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
What can kill a black hole?
There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t destroy it– the two will simply merge into a larger black hole, releasing a bit of energy as gravitational waves in the process.
Can we create a black hole?
To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. Some extensions of present physics posit the existence of extra dimensions of space.
