Answers
Answer:
hi friend here's your answer
1)Radiation from the sun pushes dust particles away from the coma, forming a dust tail, while charged particles from the sun convert some of the comet's gases into ions, forming an ion tail. Since comet tails are shaped by sunlight and the solar wind, they always point away from the sun.
2) characteristics are
- Brightness. Two characteristics define brightness: luminosity and magnitude. ...
- Color. A star's color depends on its surface temperature.
3)The collection of eight planets along with their moons rotating in their orbits around the sun is called as solar system. There are also small other species like comets, meteoroids, asteroid.
4) The planets are much smaller than the stars, planets appear to be about the same size as the stars because they are so close to us. Planets don't produce their own light. They reflect the light of the sun in the same way our moon reflects sunlight.
5) Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth – a situation known as synchronous rotation, or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
