The sun is the star at the center of our solar system. … The sun has extremely important influences on our planet: It
drives weather, ocean currents, seasons, and climate
, and makes plant life possible through photosynthesis. Without the sun's heat and light, life on Earth would not exist.
Why is the sun the most important thing on Earth?
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.
Why is the sun important facts?
The sun is a star.
This makes it
extremely important for life on Earth

Can we live without sun?
Without the Sun's rays,
all photosynthesis on Earth would stop
. … 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 without sun?
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.

78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide, helium, and neon
. Contaminants in the atmosphere can include smoke, toxic gasses, dust, ash from volcanoes, and salt.
How long would we live if the sun died?
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.
How long would we survive if the sun went out?
Likewise, if the sun simply “turned off” (which is actually physically impossible), the Earth would stay warm-at least compared with the space surrounding it-for
a few million years
. But we surface dwellers would feel the chill much sooner than that.
Is there life on the sun?
The Sun itself is not a good place for living things, with its hot, energetic mix of gases and plasma. But
the Sun has made life on Earth possible
, providing warmth as well as the energy that organisms like plants use to form the basis of many food chains.

the atmosphere would still be in motion with the Earth's original
1100 mile per hour rotation speed at the equator. … This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.

What would happen if the sun disappeared for 1 second?
What would be the short term and long term effects on Earth if the Sun suddenly vanished? …
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.
Is the sun powerful?
The amount of sunlight that hits the Earth in one hour provides more power than the entire world consumes in one year [1]. … Each hour 430 quintillion Joules of energy from the sun hits the earth. 430 quintillion is the number 430 with 18 zeroes! In contrast, all humans combined use 410 quintillion Joules in a year.
Why is the sun so special?
Compared with the billions of other stars in the universe, the sun is unremarkable. But for Earth and the other planets that revolve around it, the sun is a powerful center of attention. It
holds the solar system together
; provides life-giving light, heat, and energy to Earth; and generates space weather.
