Question

if the sun is removed all of a sudden then what will happen to the earth considering no other change will take place oin the solar system

Answer 1

The very last photons from the surface of our star and the last particles that make up the solar wind have started their final flight towards the Earth. No one would yet suspect that the heart of our solar system has stopped functioning. 8 to 9 minutes later and the sky suddenly turns black. Darkness descends upon the entire planet. No matter whether at that moment it’s the deep dark of midnight or a bright sunny noontime at your location, you can quickly and easily see the difference. The stars are now all clearly visible against the sheer black backdrop of the sky. The Moon is not visible at all since there’s no longer any sunlight to reflect. A moment before the onset of the shrouding darkness, bright Northern Lights may appear due to changes in the magnetic field around the Earth and the disturbances in the ionosphere.[1]

This will soon lead to, how shall we say it, difficulties for every living being. After an hour, true panic reigns over the heretofore day time’s side of the earth. Power and communication outages propagate across the entire planet. Temperatures everywhere drop by several degrees and the Earth surface begins to slowly cool. But from the inside, the planet is still heated by its molten core. In 24 hours, Dawn has not and will not arrive. Panic and chaos will envelop the entire world. State authorities will have almost zero control over the situation. Humankind will try to figure out what the hell happened while coping with massive power and water supply outages. The temperature on the surface falls to between 5° to 7 °C. That’s about 41° to 45 °F and will now decrease by about 15° to 20 °C. That’s a drop of about 30 °F. Some species of plants and microorganisms will begin to die. The inhabitants of the ocean by the time will feel almost no changes

After 7 days, it’s still dark. The average temperature on earth is now -17 °C. That’s about 1 °F. In areas where there are tectonic faults, it will still be warm. Thanks to geothermal energy not letting the surface freeze over. Most plants will have already died due to cold or lack of light. Herbivorous and heat-loving animals will also begin to die. In the oceans, phytoplankton will begin to die as well. The inhabitants of shallow waters will suffer tremendously from the cold and the surface of the ocean will begin to turn to ice.
