THE MOON (LUNA)

• Distance  385,000 km
• Mass  81 times lighter than the earth
• Rotation & Revolution  29 days, 7 hours, 43 minutes and 11.47 seconds
• It has 1/6th gravitational attraction than the earth
• It moves eastwards with the speed of 2100 miles per hour
• Only 59% of moon surface can be seen from earth.
• Moon’s surface is filled with crater due to non-existence of atmosphere which let meteorites come down and strike the moon surface.

THE SUN

• Distance  149 million km
• Mass  2〖 X10〗^30
• Diameter  1.4 million km
• Composition  Hydrogen 90 %, Helium 8 %, Heavy elements 2%
• Rotation  36 days
• Revolution  250 bn years around center of the galaxy
• Contains 99.86 % mass of solar system
• Source of energy is nuclear fusion – conversion of hydrogen into helium
• The surface of the sun is 4.6 billion years of age.
• The surface temperature of the sun is 6000 C while the temperature at the center is 15 million C (Photosphere & Chromospheres)
• In almost 5 billion years, when all hydrogen in its core has been used up, the sun into a red giant before becoming a white dwarf and finally will die out.
