The Moon or Lunar

14 06 2012

On July 20, 1969, Neil Armstrong became the first person who walked on the moon.

Do you ever wonder where did the moon went when at night we can’t see it or can only see a part of the moon?

I’ll explain…

The moon was not eaten or cut away.

It happened because the moon orbits the Earth.

The moon has no light and when we see the moon shines the light actually comes from the Sun.

Only half of the moon gets the light at one time.

The lighted portion of the moon that we see is called  phase of the moon.

This video might explain a lot…

Our Solar System

13 06 2012

There used to be 9 planets and more than 170 moons in our solar system.

The 9 planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.

But in August 2006, the International Astronomical Union decided to re-classify Pluto as a “dwarf planet”, and not in the same category as the 8 planets.

So now there are 8 planets in the solar system.

Each planet goes around the Sun on its own path called orbit.

Anyway we cannot see the paths because they are invisible.

Earth takes about 365 days to orbit the Sun.

This is called one Earth year.

And each moons moves around its planet in its own orbit.

The size of the planet from the smallest to the biggest:

  1. Mercury

  2. Mars

  3. Venus

  4. Earth

  5. Neptune

  6. Uranus

  7. Saturn

  8. Jupiter

On April 12, 1961, Yuri Alekseyevich Gagarin became the first person who went to space.

People travel to space in a spacecraft or spaceship.

This is space shuttle Discovery’s final landing.

It is NASA’s most traveled spaceship.

Since 1984, Discovery flew 39 missions, spent 365 days in space, orbited Earth 5,830 times and traveled 148,221,675 miles.

Discovery’s first flight was from August 30, 1984 to September 5, 1984.

It’s final flight was from February 24, 2011 to March 9, 2011.
