- Space is Completely quiet
Sound doesn’t have the ability to travel at all in space. The vacuum
has practically 0 air Because Sound is basically vibrating air, outer space has zero air to vibrate and therefore no sound. If you were on the moon and saw a explosion, you wouldn’t hear absolutely nothing. This fact is the 2nd most interesting to me and I use to thought that you could hear things in space like you do on earth.
2. There is more trees on earth than there is stars in the milky way galaxy
The estimated trees in the world is around 3.04 trillion while there is a estimated 100-400 billion stars in the vast milky way galaxy. Approximately 1.30 trees reside in tropical and subtropical forests, 0.74 trillion in boreal regions and o.66 trillion in temperature regions. According to NASA Education, many estimates put the estimated number of stars in the milky way galaxy at 100 billion and 400 billion sun’s. That’s a lot of trees
3. A day on mercury is twice as long as a year
A year on mercury is right about 88 earth days long. A solar day on mercury is 2x as long its year, or 176 earth days long. This is due to the fact that of slow rotation of mercury around its axis. Imagine spending a 1,408 hour day
4. It takes a million Earth’s to fit the volume of our sun
Our sun is so massive it would take over a million Earth’s to fill it up. Size sometimes does matter
5. It would take 9 years if you were to walk to the moon.
The moon is Earth’s only natural satellite. In the image seen above, the distance between earth and the moon is about 384,400 kilometers. Meaning it would take about a decade to walk to the moon. Imagine how many calories you would 🔥 burn.
