If the Earth's orbit around the Sun were shorter, that would imply it would be closer to the Sun and thus be subject to increased incident solar radiation - per the inverse square rule. For example, half the distance would be four times the amount of sunlight. This would cause the average temperature on Earth's surface to increase.
Earth
No, it does not.
Mercury and Venus both have shorter years than Earth does. They are closer to the sun and the orbit is shorter than Earth's.
Seasons happen because of Earth's revolution.
u die ....
revolution of earth around the sun causes the variation in the temperature..
The average temperature would go up and the year would get shorter.
The core temperature of Sun is 14 million kelvin. The outermost temperature is about 6000 K. So due to this higher temperature and heat radiations from it the earth would burn definitely. May be the speed of revolution may be increased to a large value. And spinning of earth too will be terribly affected. Any way earth itself would be burnt into ashes.
Weather patterns may be more severe and ultimately - days will be shorter.
It depends how close. A mile wouldn't matter, but 100,000 miles and we would probably feel the heat.
It gets hotter
Both temperature and pressure increase as depth increases.
