What is a solar system Grade 8
The Solar System: The sun and the celestial bodies such as planets, comets, asteroids and meteors which revolve around the sun form the solar system. The sun is the nearest star which is the main source of heat and light for all the planets. The planets do not emit light from their own like stars.
What are the objects around the Sun Grade 8
It consists of a large number of celestial bodies such as planets, comets, asteroids, and meteors. The gravitational attraction between the Sun and these objects keeps them revolving around it. There are 8 planets revolving around the Sun. They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
What can I write about the solar system
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
What are the properties of stars Class 8
Answer: Stars are celestial objects that can produce their own light. They are extremely hot and extremely large in size. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star which is nearest to us.
How is a star different from a planet
A star is a body that possesses a light that causes it to reflect the light independently. On the other hand, a planet is simply a fixed celestial body with its own orbit and spins on its own axis, yet reflects the light from an external source.
What is the difference between star and planet for Class 8
Stars consist of matter like Hydrogen, Helium, and other light elements. Planets, on the other hand, contain solids, liquids, gases, or a combination thereon. Thus, this is the basic difference between stars and planets.
How big is the star in the sky
Stars range in size from neutron stars, which can be only 12 miles (20 kilometers) wide, to supergiants roughly 1,000 times the diameter of the sun. The size of a star affects its brightness. Specifically, luminosity is proportional to radius squared.
How does a planet differ from a star
A star is a body that possesses a light that causes it to reflect the light independently. On the other hand, a planet is simply a fixed celestial body with its own orbit and spins on its own axis, yet reflects the light from an external source.
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 a star Class 7
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.
What is the difference between a star and a planet Class 8
Difference between Stars and Planets
Stars are huge celestial bodies made up of hydrogen and helium that can emit their light and energy from nuclear fusion reactions. Planets are celestial bodies that orbit around the Sun. They don't have the ability to emit light and energy from nuclear fusion reactions.
What makes a star a star and not a planet
Unlike stars, planets do not experience nuclear fusion, the process of combining tiny particles called atoms to release energy. Nuclear fusion creates radiation (heat and light) and makes stars glow. Because planets do not have nuclear fusion, they do not produce their own light.
What defines a planet vs star
Unlike stars, planets do not experience nuclear fusion, the process of combining tiny particles called atoms to release energy. Nuclear fusion creates radiation (heat and light) and makes stars glow. Because planets do not have nuclear fusion, they do not produce their own light.
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.
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.
What is a star short answer
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.
What are stars made of for kids
Stars are huge balls of burning gases, most of which are made of hydrogen. As the hydrogen gas in a star is squeezed due to gravity, it produces huge amounts of energy, which make it glow. The size, temperature, brightness, and color of stars vary. The color of a star is determined by its temperature.
What is a star Grade 9
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 a star Grade 5
Stars are huge balls of burning gases, most of which are made of hydrogen. As the hydrogen gas in a star is squeezed due to gravity, it produces huge amounts of energy, which make it glow.
Why do stars twinkle
The stars seem to twinkle in the night sky due to the effects of the Earth's atmosphere. When starlight enters the atmosphere, it is affected by winds in the atmosphere and areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.
What defines a star
star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. Of the tens of billions of trillions of stars composing the observable universe, only a very small percentage are visible to the naked eye.
Why is a star not a planet
Unlike stars, planets do not experience nuclear fusion, the process of combining tiny particles called atoms to release energy. Nuclear fusion creates radiation (heat and light) and makes stars glow. Because planets do not have nuclear fusion, they do not produce their own light.
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 the description of a star for kids
A star is a giant ball of very hot gas, mainly hydrodgen and helium, held together by a force called gravity. Inside the star's core, hydrogen atoms crash into each other and make helium. This process is called nuclear fusion and the energy it releases makes the star shine.
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.
