What is a star for kids
STAR DEFINITION. 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 is star in the sky
Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy.
What is the description of a star
A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements.
Why is called a star
Stars are space objects that produce their own energy through fusion reactions of gasses. They are like round, gas burning, energy producing luminous orbs. Sun- the star of our solar system is a star because it produces energy by the fusion reaction of Helium turning into Hydrogen.
What are stars for Class 6
Stars are celestial objects that can produce their own light. They are extremely hot and extremely large. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star; the sun's energy and light play one of the key roles in sustaining all forms of life on earth.
What is star for class 3
Stars are balls of hot, explosive gas that make their own light and heat energy. They're mostly made up of two gases called hydrogen and helium.
What is star Class 8
Stars are celestial objects which emit their own light like the sun. Some examples of stars are – pole stars – stationary stars, Sirius – the brightest star, etc. The Sun and the celestial bodies which revolve around it form the solar system.
What are stars made up of
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
What is a star definition for Class 6
Stars are celestial bodies made up of gases; they are huge in size and have very high temperatures. Planets are the celestial bodies that do not have their own heat and light. They have their own heat and light, which they emit in large amounts. They are lit by the light of stars. For example, the Sun is a star.
What is the best description of stars
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
What is a star made of
A star is a huge glowing ball of hot gas. Deep inside its core, hydrogen atoms smash together, forming helium and releasing huge amounts of energy that heats the gas. This is called nuclear fusion, and it's why a star shines. As the hot gas pushes outward, it opposes the inward pull of gravity.
How is a star born
Stars form from collapsing clouds of gas and dust. Astronomers can train telescopes on giant clouds of hydrogen gas in our own galaxy and find knots of denser, colder gas and dust that are in the process of giving rise to stars. These dust-thick regions of star birth are often dark and opaque.

Stars are celestial objects which emit their own light like the sun. Some examples of stars are – pole stars – stationary stars, Sirius – the brightest star, etc. The Sun and the celestial bodies which revolve around it form the solar system.
What is star Class 9
Stars are celestial objects which emit heat and light on their own. They also produce ultraviolet rays, x-rays, and many other forms of radiation. Stars are mainly composed of hot gases, like hydrogen and helium, along with a superheated state of matter called plasma.

They have their own heat and light, which they emit in large amounts. They are lit by the light of stars. For example, the Sun is a star.
What is a star class 10
Stars are celestial objects that can produce their own light. They are extremely hot and extremely large. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star; the sun's energy and light play one of the key roles in sustaining all forms of life on earth.
What is star class 11
A star is a massive ball of hot, glowing matter in space. That substance is known as plasma. Gravity holds stars together. Because they are red and small, the smallest stars are known as red dwarfs. The stars like our sun are the next category up.
How is a star made
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.
Are stars made of Earth
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores.
What is a star 5th grade
And colors temperatures and brightness. And sometimes have unusual characteristics the closest star to Earth is our own Sun. Like everything else in nature Stars Are Born live out their days.
What are stars made of
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
What is star light description
Starlight is the light emitted by stars. It typically refers to visible electromagnetic radiation from stars other than the Sun, observable from Earth at night, although a component of starlight is observable from Earth during daytime.
What are stars 98% made up of
About 98% of the mass of the universe is made up of only two types of atoms: hydrogen and helium. That's because these two elements make up stars like our sun and most of the stars in the universe.
How long does a star live
Giant stars use up their hydrogen fuel quickly, resulting in short lifetimes. An eight solar mass star will live less than 100 million years. At 10-15 solar masses, the lifetime of the star drops to only 10-20 million years. The most massive giant stars are believed to live no more than a few million years.
What is star class 12
Stars are celestial objects that can produce their own light. They are extremely hot and extremely large. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star; the sun's energy and light play one of the key roles in sustaining all forms of life on earth.
