The stars emit their own light.
a)
True
b)
False

Anita Menon answered |
Stars, including the Sun, emit light because deep down at the core of a star there are nuclear fusion reactions happening. These reactions produce an enormous amount of heat and light. Most objects in space, other than stars, reflect light. For example, planets like Venus, Mars , Jupiter and saturn all reflect light.

The answer is a.
Venus is one of the brightest objects in the night sky. Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth.

Divya Das answered |
The stars, planets, moon, and objects in the sky are called celestial bodies.
Explanation:
Celestial bodies refer to any natural objects that exist in space, such as stars, planets, moons, asteroids, comets, and galaxies. These bodies are typically observed in the night sky and have fascinated humans for centuries. Here is a breakdown of the different types of celestial bodies:
1. Stars:
Stars are massive, luminous balls of gas that emit light and heat due to nuclear reactions occurring in their cores. They are composed mostly of hydrogen and helium and are responsible for illuminating the night sky. Stars come in various sizes, colors, and brightness levels, and they exist in vast numbers throughout the universe.
2. Planets:
Planets are celestial objects that orbit around a star and do not produce their own light. In our solar system, we have eight planets, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Planets are typically solid or gaseous bodies and can vary significantly in size, composition, and atmospheric conditions.
3. Moon:
The moon is Earth's natural satellite, and it orbits around our planet. It is relatively small compared to planets but is still a significant celestial body. The moon reflects sunlight, allowing us to see its illuminated surface at night. It plays a crucial role in Earth's tides and has been a subject of fascination and exploration by humans.
4. Asteroids and Comets:
Asteroids are rocky objects that orbit the sun, primarily found in the asteroid belt between Mars and Jupiter. They can range in size from small rocks to larger bodies several hundred kilometers in diameter. Comets, on the other hand, are icy bodies that also orbit the sun but have a tail that forms when the sun's heat causes the comet's ices to vaporize.
5. Galaxies:
Galaxies are vast systems of stars, gas, and dust that are held together by gravity. They come in different shapes and sizes, ranging from spiral galaxies like our Milky Way to elliptical and irregular galaxies. Galaxies can contain billions or even trillions of stars and are considered the building blocks of the universe.
In conclusion, celestial bodies encompass a wide range of objects, including stars, planets, moons, asteroids, comets, and galaxies. They are awe-inspiring and play a crucial role in our understanding of the universe and our place within it.

|
Anoushka Singh answered |
The seasons are caused as the Earth,
on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. As the Earth travels around the Sun, the hemisphere that is tilted towards or away from the Sun changes.
tilted |  |
The hemisphere that is tilted towards the Sun is warmer because sunlight travels more directly to the Earth’s surface so less gets scattered in the atmosphere. That means that when it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere.

We see constellations at different times of the year- spring, summer, fall, and winter. This occurs because the Earth is orbiting the sun. But in summer, we see the opposite ( we see Scorpius at night and Orion is in the sky during the day) . This is why you cannot see orion or any one constellation all year long.

Mohit Sengupta answered |
Hot gases
The sun and other stars are huge bodies primarily made up of hot gases. These gases are mainly composed of hydrogen and helium, with small amounts of heavier elements. The immense pressure and temperature at the core of these stars cause nuclear fusion reactions to occur, converting hydrogen into helium and releasing vast amounts of energy in the form of light and heat.
Composition
The sun, for example, is composed of approximately 70% hydrogen and 28% helium, with trace amounts of heavier elements like oxygen, carbon, and nitrogen. These gases are in a plasma state, where the particles are highly energized and move freely, creating the intense heat and light that we see emanating from stars.
Nuclear Fusion
Nuclear fusion reactions within the core of stars occur when hydrogen atoms fuse together to form helium, releasing energy in the process. This process powers the sun and other stars, providing the heat and light necessary for life on Earth.
Temperature and Pressure
The temperatures at the core of stars can reach millions of degrees Celsius, while the pressure is immense due to the gravitational forces acting on the gases. This combination of high temperature and pressure is what sustains the nuclear fusion reactions and keeps the stars shining brightly.
In conclusion, stars like the sun are primarily composed of hot gases, particularly hydrogen and helium, which undergo nuclear fusion reactions to produce energy. These reactions sustain the stars' immense heat and light output, making them crucial sources of energy in the universe.

An object orbiting around the sun, earth or any other colossal body is known as a satellite. There are two major types of categorization when it comes down to satellites, one is natural and the other is man-made.
Some of the examples of natural satellites are planets, moons, and comets. Jupiter has 67 natural satellites. The earth has one permanent natural satellite, the moon we know, which causes the tides in the sea.

Star, moon and planets are celestial bodies as they are located in sky but artificial satellite made by human beings revolves around the earth in fix orbit for fix interval of time.
