Question

give long answer for the following question ( 50-60word)
a. write the main features of the sun
b. discuss the various phases of the moon
c. what is planet
d. what is solar system​

Answer 1

Answer:

• The main part of the Sun has three layers: the core, radiative zone, and convection zone. The Sun's atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
• Crescent refers to phases where the Moon is less than half-illuminated, while gibbous means more than half is illuminated. Waxing means “growing” or expanding in illumination, and waning means “shrinking” or decreasing in illumination. After new Moon, a slice of reflected sunlight becomes visible as a waxing crescent.
• A planet is a large celestial body that revolves around the sun in fixed orbits. Planets do not have any light of their own but reflect the light of the sun. Planets also do not twinkle like stars because they are much closer to us.
• Solar System is the collection of eight planets and their moons in orbit round the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets. The planets of the solar system are (in order of distance from the sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Answer 2

Answer:

(a) The main part of the Sun has three layers: the core, radiative zone, and convection zone. The Sun's atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.

(b)Crescent refers to phases where the Moon is less than half-illuminated, while gibbous means more than half is illuminated. Waxing means “growing” or expanding in illumination, and waning means “shrinking” or decreasing in illumination. After new Moon, a slice of reflected sunlight becomes visible as a waxing crescent.

(c) A planet is a large celestial body that revolves around the sun in fixed orbits. Planets do not have any light of their own but reflect the light of the sun. Planets also do not twinkle like stars because they are much closer to us.

(d) The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies.
