The planets in the sky would follow suit, disappearing one by
one as the wave of darkness reached them
. Eventually, though, the lack of the Sun's radiation would leave us pretty chilly. … The atmosphere itself would also freeze and fall to Earth, leaving us exposed to the harsh radiation travelling through space.
What would happen if there was no sun for a year?
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.
What would happen if the Sun disappeared forever?
With no sunlight,
photosynthesis would
stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after.
How long would we survive if the Sun disappeared?
A relatively simple calculation would show that the Earth's surface temperature would drop by a factor of two
about every two months
if the Sun were shut off. The current mean temperature of the Earth's surface is about 300 Kelvin (K). This means in two months the temperature would drop to 150K, and 75K in four months.
What happens if the Sun goes out for 1 second?
The Sun has been responsible for giving our planet energy over the last 4.5-billion years. … 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 would happen if the moon broke apart?
If the moon exploded,
the night sky would change
. We would see more stars in the sky, but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter, and our ocean tides would be much weaker.
What will happen if the Earth stops rotating?
At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped,
the momentum would send things flying eastward
. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
What will happen when the sun dies?
After the
Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury
. Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. … While the Sun won't become a red giant for another 5 billion years, a lot can happen in that time.
Which planet would I weigh the most?
Jupiter
is the largest planet in our Solar System with the most mass. Because of Jupiter's mass, you would weigh more on that planet than on any other one in our Solar System. If you weighed 68 kg on Earth then you would weigh 160.7 kg on Jupiter, over twice your normal weight.
What would the Earth be like if there is no sunlight?
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.
Would the Earth survive without the moon?
Without the moon, we would see
an increase in wind speeds
. … The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Can the sun explode?
Scientists have conducted a lot of researches and study to estimate that
the Sun is not going to explode for another 5 to 7 billion years
. When the Sun does cease to exist, it will first expand in size and use up all the hydrogen present at its core, and then eventually shrink down and become a dying star.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin
(about minus 455 degrees Fahrenheit)
. But space is mostly full of, well, empty space.
What happens if the sun disappears for 5 seconds?
Scientists estimate that the Sun will die in around 5 billion years. If the Sun miraculously disappeared, the Earth (and all the other objects in the Solar System) would
continue their forward motion in a straight line off into space
, instead of following their almost-circular orbits.
What if the sun stopped shining for a second?
If the sun disappears,
nothing will keep planets in orbits
. They will be drifting outside the solar system till they get under a stronger gravitational force of another object. Or until the moment they'll crash into a large space object.
Why does it take so long for the sun to burn out?
The sun, like the rest of the universe, is made mostly of hydrogen. There isn't enough oxygen in the entire solar system to keep the surface of the sun burning through chemical combustion for more than a very short time—probably hours.
