. … A planet is a celestial body that orbits around the star in its solar system and gets its glow from the suns light reflecting from the planets face.
How does a star differ from a planet Class 6?

the bending of the light changes too
, which causes the star’s appearance to wobble or twinkle.

Are constellations are close clusters of stars all at about the same distance from the Sun?
Constellations are close clusters of stars, all at about the same distance from the sun. Only at the equator are all the stars visible over the course of year. Over the course of a night, Polaris moves less than any other visible star in the sky. From Earth, the sun and moon have about the same angular diameter.
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 star color is the hottest?
White stars are hotter than red and yellow.
Blue stars
are the hottest stars of all.
Do stars twinkle in space?
Similarly, stars twinkle because their light has to pass through several miles of Earth’s atmosphere before it reaches the eye of an observer. … In outer space, where
there is no atmosphere, stars do not twinkle
.
Is the sun White?
The range of colors, or frequencies in a beam of light is called a spectrum. When we direct solar rays

is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
