1. The distance between the sun and earth is 1.5x1011metres[150,000,000,000metres]
A light ray travels three lakh kilometers[3,00,000km] in one second.
Light year is the distance but a light ray travels in one year in vaccum is about
9.5x1015 meters.

The distance between the surface of the earth and the sun = 1.496x1011m
The Sun takes one month to make one revolution around its own axis. It
takes 26000 years to make one complete revolution around the universe.
The temperature of Sun’s surface is 6000 Celsius and all the metals get
vaporized at this temperature.
The Mercury orbits around the Sun with fastest speed. It completes its
revolution around the Sun in 88 days.
The Venus is the hottest planet of the solar system and its temperature
reaches the mark of 460 Celsius.
The duration of one day of the Mars is few minutes more (24 hours 37
minutes 23 seconds) than that of one day of the earth.
We shall be reaching on the Moon in around 100 days if we move
towards it with a speed of 160 kilometers per hour.

2. The distance of the Moon from the earth is increasing with a speed of 3
centimeter per year.
Only one part of the Moon is visible from earth because it takes equal
time to revolve around its orbit and its axis.
The earth is moving on its axis with a speed of 1600 kilometers per hour
and 1 lakh kilometers per hour around Sun.
If the earth is compared to an apple then the thickness of the
atmosphere above earth shall be equivalent to the bark of it.
The heat of the Sun vaporizes around 1 lakh cubic miles of water per
year which weighs around 4 crores of tons.
The 71% portion of surface of the earth is covered with water, the 97%
of which is salty and only 3% sweet.
Our earth is closer to the Sun during winters. During winters it comes
closer to the Sun by 50 lakhs kilometers and in summers it goes away
from the Sun by same distance. The temperature in summers is up not
due to distance but the angle earth's surface makes towards Sun.

Planet Saturn is lighter than water and the weight of Jupiter is more
than total weight of all planets.
