Can a telescope see the flag on the moon?
Yes, the flag is still on the moon, but you can’t see it using a telescope.
The Hubble Space Telescope is only 2.4 meters in diameter – much too small.
Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter..
What would happen if the moon disappeared?
It is the pull of the Moon’s gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
Has anyone died in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle.
How long would it take for the moon to crash into the earth?
That needs about 60 days, or 2 moon orbits. It will change its orbit during those 60 days, so the calculation is not very accurate, but it gives the right timescale. So the moon would come closer to Earth and crash within a few months.
Would we die if there was no sun?
All plants would die and, eventually, all animals that rely on plants for food — including humans — would die, too. While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.
Does the earth attract the moon with a greater force?
Answer: According to universal law of gravitation and Newton third law, we know that the force of attraction between two objects is same but in opposite direction. Thus the earth attracts the moon with the same force as the moon exerts on earth but in opposite directions.
Where is the value of G equal to zero on Earth?
Acceleration due to the earth’s gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. As the distance from the centre decreases, the acceleration due to gravity also decreases.
Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.
Why the earth does not move towards the moon?
As we know, the mass of earth is much larger as compared to the mass of the moon, it cannot produce significant acceleration in earth for it to move towards the moon. Therefore, earth does not move towards the moon.
How does the moon keep Earth stable?
The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet’s wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
Why does the earth not move?
The spinning and orbital speeds of Earth stay the same so we do not feel any acceleration or deceleration. You can only feel motion if your speed changes. For example, if you are in a car which is moving at a constant speed on a smooth surface, you will not feel much motion.
Can the moon crash into Earth?
But, in fact, the Earth and Moon may be on a very long-term collision course — one that incredibly some 65 billion years from now, could result in a catastrophic lunar inspiral. … This recession is due to tidal friction caused by the effects of the Moon’s gravitational tides on the Earth, Barnes told me.
What if the moon was habitable?
If we had a habitable moon, it would have to have its own magnetic field to shield us from cosmic rays, it would have to have the right atmospheric conditions, it’s micro organisms would have to be compatible with us and any food we hoped to grow.
Is the flag still on the moon?
A review of photographs taken by the Lunar Reconnaissance Orbiter (LRO) indicates that flags placed during the Apollo 12, Apollo 16, and Apollo 17 missions were still standing as of 2012.
