Moon talk- everything you need to know about our neighbor

    Here is some facts about the moon:

    • The moon orbits the Earth at an average speed of 2,300 miles an hour (3,700 kilometers an hour).

    • The airless lunar surface bakes in the sun at up to 243 degrees Fahrenheit (117 degrees Celsius) for two weeks at a time (the lunar day lasts about a month). Then, for an equal period, the same spot is in the dark. The dark side cools to about -272 degrees Fahrenheit (-169 degrees Celsius).

    • The rocks and soil brought back by Apollo missions are extremely dry; the moon has no indigenous water. However, the moon is bombarded by water-laden comets and meteoroids. Most of this water is lost to space, but some is trapped in permanently shadowed areas near both poles of the moon.

    • The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest. Both bulges cause high tides. These are high tides. As the Earth rotates, the bulges move around it, one always facing the moon, the other directly opposite. The combined forces of gravity, the Earth's rotation, and other factors usually cause two high tides and two low tides each day.

    • To the unaided eye, the bright lunar highlands and the dark maria (Latin for "seas") make up the "man in the moon." A telescope shows that they consist of a great variety of round impact features—scars left by objects that struck the moon long ago. The largest scars are the impact basins, ranging up to about 1,500 miles (2,500 kilometers) across. The basins were flooded with lava some time after the titanic collisions that formed them. The dark lava flows are what the eye discerns as maria.

    Interesting. The moon has been here for a very long time, and helps keep the Gravity safe. I love our moon.

    I too love our Moon. Thanks for reading.

    I remember when I had learned that there was once lava seas on the Moon. My mind instantly sprang to a Star Wars like vision. xD

    The moon is gradually falling away from Earth's orbit. In ancient times the moon was 3x larger in the sky than it is today.

    The moons surface has been the same since it's creation, as there's no wind, water, or any elements to erode it.

    A compass would not work on the moon, as there is no magnetic field.

    Wow. I didn't know that last one xD

    I remember reading that the moon is slowly moving away from the earth. I wonder what it must have been like 50,000 years ago, to sit and look at the moon? How much bigger would that moon look as compared to today?
    Uhmmm. Interesting thought.

    Wow I don't know what to say, That is probably one of my favorite object in the night sky to observe. It is kind of profound to think that Everyone on this planet with vision has at one point or another has seen the EXACT same object and it has not changed in all that time.
