Apollo 11’s ‘third astronaut’ reveals secrets from dark side of the moon | 60 Minutes Australia

Can moons have moons?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

informal. : a very long time I visited my old school yesterday for the first time in many moons. But that was all many moons ago.

What if the sun disappeared for 1 second?

Eternal night would fall over the planet and Earth will start traveling into interstellar space at 18 miles per second. Within 2 seconds, the full moon reflecting the sun's rays on the dark side of the planet would also go dark.

What is Earth's second moon?

Its period of revolution around the Sun, approximately 364 days in the early 21st century, is almost equal to that of Earth. Because of this, Cruithne and Earth appear to "follow" each other in their paths around the Sun. This is why Cruithne is sometimes called "Earth's second moon".

What would happen if the Earth stopped spinning for 42 seconds?

Assuming that the earth stops suddenly for 42 seconds and then starts spinning again at its normal speed, here's what would happen: 1. If the earth stops spinning suddenly, the atmosphere will continue to spin. This means very high speed winds, i.e., approximately 1,670 Km/hr which is earth's rotational velocity.

What is Earth named after?

All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words 'eor(th)e' and 'ertha'. In German it is 'erde'.

Could the Earth stop spinning?

As the Earth spins, these bulges move across the Earth's surface like a wave, pushing against the Earth's spin. This slows down the Earth's spin. It means that Earth's day lengthens by one second every 50,000 years. The only thing that could stop the Earth's spin would be if another planet crashed into it.

Is dust a space?

The Universe is a very dusty place. Cosmic dust consists of tiny particles of solid material floating around in the space between the stars. It is not the same as the dust you find in your house but more like smoke with small particles varying from collections of just a few molecules to grains of 0.1 mm in size.
