How well do you know Earth's Moon? How did it form, rotation, its orbit? Get up close and familiar- 5 points

1/5 How did the Moon form? According to the information provided by NASA, the leading theory behind the formation of the Moon is that a Mars-sized object collided with Earth billions of years ago, and debris from this collision eventually formed the Moon. (NASA)

2/5 Moon's rotation: The time it takes for the Moon to rotate once on its axis is equal to the time it takes for the Moon to orbit once around Earth. This keeps the same side of the Moon facing towards Earth throughout the month. (NASA)

3/5 Moon orbit Earth: According to NASA, the Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon). As the Moon completes each 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun. Because of this change in position, sunlight appears to hit the Moon at a slightly different angle on day 27 than it does on day zero ― even though the Moon itself has already traveled all the way around Earth. It takes a little more than two additional days for sunlight to hit the Moon in the same way it did on day zero. This is why it takes 29.5 days to get from new moon to new moon, even though it doesn’t take quite that long for the Moon itself to travel once around Earth. (NASA)

4/5 Does the Moon have gravity? What would happen if there was no Moon? The Moon does have gravity. Because the Moon has less mass than Earth, its gravitational pull is weaker (about one-sixth of Earth’s). On the Moon, you will be able to jump about six times as high as you can on Earth ― but you would still come back down, informs NASA. Also, If there would be no Moon, Earth would be a very different world. The Moon’s gravity keeps our planet from wobbling on its axis too much, which helps to stabilize our climate. The Moon also plays an important role in creating tides in Earth’s oceans. (NASA)

5/5 Who Has Walked on the Moon? Neil Armstrong and Edwin "Buzz" Aldrin were the first of 12 human beings to walk on the Moon. Four of America's moonwalkers are still alive: Aldrin (Apollo 11), David Scott (Apollo 15), Charles Duke (Apollo 16), and Harrison Schmitt (Apollo 17). In all, 24 American astronauts made the trip from Earth to the Moon between 1968 and 1972. Three astronauts made the journey from Earth to the Moon twice: James Lovell (Apollo 8 and Apollo 13), John Young (Apollo 10 and Apollo 16), and Gene Cernan (Apollo 10 and Apollo 17). (NASA)

Those of us who have gone through a mid-life crisis know that it is a period of really big emotional turmoil. Everyone who reaches a certain age goes through it. Now, it has been revealed that not even massive celestial bodies like the Sun are safe from it. And yes, that also indicates that our Sun will die too.

A new study by the European Space Agency (ESA) has revealed that the Sun has entered its middle age, estimated to be around 4.57 billion years. It seems that the Sun is also going through a mid-life crisis with frequent Solar Flares, Coronal Mass Ejections (CMEs) and Solar Storms. The study was conducted with the help of data collected by the Gaia spacecraft.

Currently, the Sun is at the peak of its 11-year solar cycle, which has resulted in frequent solar flares, coronal mass ejections and solar storms. As the cycle ends, the frequency of these phenomena will decrease.

As the Sun gets older, the hydrogen in the Sun's core will run out and the Sun will turn into a giant red star, lowering its surface temperature and cooling off. According to the ESA, as the Sun will reach the end of its life cycle, it will become a dim white dwarf star.

Orlagh Creevey from Observatoire de la Côte d'Azur, France searched through the data by studying some of the oldest stars in the Milky Way Galaxy with surface temperatures between 3000K and 10,000K. Orlagh said, “We wanted to have a really pure sample of stars with high precision measurements.”

The study concluded that the Sun will reach its peak temperatures nearly 8 billion years into the future after which it will lower its surface temperature and increase its size.

Orlagh said, “If we don't understand our own Sun and there are many things we don't know about it how can we expect to understand all of the other stars that make up our wonderful galaxy.”

NASA, on the other hand, had earlier sad in its report, "When it starts to die, the Sun will expand into a red giant star, becoming so large that it will engulf Mercury and Venus, and possibly Earth as well. Scientists predict the Sun is a little less than halfway through its lifetime and will last another 5 billion years or so before it becomes a white dwarf."
