MOON – A Brief Introduction

The earth has only one natural satellite called moon. It is also called dead satellite.
Moon’s gravity is just 1/6 of earth’s gravity. It is only 1.62m/s².

A large size terrestrial body collide with earth 4.53 billion years ago and a large piece of earth is separate and revolve in orbit around earth. Now that large piece is our moon.

Due to moon’s less gravity, there is no atmosphere on the moon because the escape velocity of atmospheric particle is greater than the escape velocity of moon and due to this the atmospheric particle escape out of moon’s gravitational pull.

Moon’s escape velocity is only 2.38km/sec while earth’ escape velocity is 11.19km/sec.

Moon complete one revolution of earth in just 29.4 days While earth can complete one revolution of sun in 365.25 days.
Moon can complete one revoution on its axis in 27.3 days.

Earth’s one day time 23 hours and 56 minutes. This is the cause of leap year.

According to some theories if moon does not exist then earth’s day time would be approximately 6 to 10 hours. So moon increase earth’s day time.

Moon’ gravity cause tides in sea.

Thousands of asteroid and comets was collides with moon’s surface and cause craters on its surface. You can see these craters from earth by telescope.

The first living animal land on the moon surface was a dog name Laika on 3 November 1957.
And The man who took the first steps on the moon’s surface on july 20, 1969, was named Neil Armstrong .

Neil Armstrong and aldrin walked on surface of the moon.

Radius of the moon is approximately 1,738 km Earth to moon distance is 384400kms.
Light can take 1.2 second to reach the moon from earth.

    1. Dear Penser,
      I concur with Jessica, though I admire the spirit and effort that you have put into this post.
      What else can I say but to resonate with the tenet and spirit of your post with my special poem published in the post entitled “🎴 If My Name Were Moon Tonight… 🌛🌝🎑🈷 with Clair de Lune 🌕”, where I hope that you will snap up the chance to watch my dynamic animation produced in high resolution (1920 x 1280) at
      The animation starts calmly and will gradually climax. The post also comes with my rhyming poem and musical performance. Please enjoy the animation on the big high-resolution screen of your desktop or laptop computer.
      Happy mid-December to you!

    2. Dear Penser and Jessica,

      Hello! You are very welcome, Penser. Please be informed that you might need to use a desktop or laptop computer with a large screen to view the rich multimedia contents available for heightening your multisensory enjoyment at my blog, which could be too powerful and feature-rich for iPad, iPhone, tablet or other portable devices to handle properly or adequately.

      In addition, since my posts and pages contain advanced styling and multimedia components plus animations, it is highly recommended to read my posts and pages directly on the blogs or websites where I have published them, so that you will be able to see and experience all of the refined and glorious details. Hence, it is prudent to refrain from using the WordPress Reader to access my blogs or websites because WordPress Reader can be considerably limited in how closely it reproduces contents of certain blogs or websites, given that it has to deal with a wide range of blogs or websites. It tends to ignore or strip away some styling and formatting components, and also fails to display animations, all of which are aplenty in my posts and pages. As a result, a post or page can look very different and even improper or amiss on the WordPress Reader. So, I tend to read posts and pages directly on the blogs or websites where they are published, especially when they contain animations, advanced styling and detailed intricacies like mine.

      May you and Jessica find this winter and the rest of the year very much to your liking and highly conducive to your writing, thinking and blogging!
