What is a Star Class 5?
A simple science lesson and fun video on the solar system for kids in 3rd, 4th and 5th grade! A star is
an exploding ball of burning gas held together by gravity
. Our sun is a star! It produces great amounts of energy in the form of light and heat that provide the perfect conditions for life on Earth.
What are the 5 main groups of stars?
- Supergiants.
- Giants.
- Main sequence.
- White dwarfs.
What are the 7 main types of stars?
There are seven main types of stars. In order of decreasing temperature,
O, B, A, F, G, K, and M
. This is known as the Morgan–Keenan (MK) system.
What is the biggest star?
The cosmos is full of objects that defy expectations. Although it’s difficult to pin down the exact traits of any given star, based on what we know, the largest star is
UY Scuti
, which is some 1,700 times as wide as the Sun.
What is star life cycle?
A star’s life cycle is
determined by its mass
. … As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts.
How is a star born step by step?
A star is born when atoms of light elements are
squeezed under enough pressure for their nuclei to undergo fusion
. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
How long do stars live for?
Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only
a few million years of fusion
. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.
What color is the hottest star?
White stars are hotter than red and yellow.
Blue stars
are the hottest stars of all.
What classification of stars is the coolest?
The spectral sequence is also a colour sequence: the O- and B-type stars are intrinsically the bluest and hottest; the
M-, R-, N-, and S-type stars
are the reddest and coolest.
What is star give example?
Star is defined as a bright point of light in the sky or a five-sided drawing that is meant to resemble the points of light in the sky. An example of star is
what makes up the Big Dipper constellation
. An example of star is a drawing of a five-sided point of light.
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving,
the bending of the light changes too
, which causes the star’s appearance to wobble or twinkle.
What is a huge system of stars is called?
A huge system of Stars is called
a Galaxy
which is a gravitationally bound system of stars, interstellar gas, dust, stellar remnants, and dark matter ranging in size from very small having a few hundred million stars to giants with one hundred trillion stars, each orbiting its galaxy’s center of mass.
