Does the moon have any satellites?
Answer: I believe that there is only one known artificial satellite orbiting the Moon at the moment, that being the Lunar Reconnaissance Orbiter (LRO). The LRO is only about 5 meters in size, which would make it appear to be an unresolved point of light from Earth.
What the Earth would be like if there were no sun?
Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
How long would it take for us to know if the sun exploded?
eight minutes and twenty seconds
What if Sun became a black hole?
What if the Sun turned into a black hole? The Sun will never turn into a black hole because it is not massive enough to explode. Instead, the Sun will become a dense stellar remnant called a white dwarf.
What would we see if the sun exploded?
If the sun suddenly blew up, we actually wouldn’t know it happened for — you guessed it — eight minutes, 20 seconds — since even that explosive light show would only be traveling, at maximum, the speed of light. The death and destruction would follow very, very shortly after that.
Why did the sun go dark for a second?
Here’s what that means. The sun is blank for the second time in less than a month — not a single dark sunspot mars its surface. It’s a sign our star is entering a new period of decreased activity — one that will continue to last for about five years.
How does the sun burn without oxygen?
The sun does not run out of oxygen for the simple fact that it does not use oxygen to burn. The burning of the sun is not chemical combustion. It is nuclear fusion.
What does the sun burn for fuel?
The Sun produces a large amount of energy by combining very light elements such as hydrogen to heavier elements such as helium and then lithium, oxygen, carbon, right up to iron.
Is the Sun Fire or plasma?
It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter. As we heat up a solid it becomes liquid.
