Pretty freakin close. But then again if the Sun even got that close we'd all die =P. I think the boiling point for water is like 212 degrees Fahrenheit, so if the sun moved like where Venus is, the oceans probably would evaporate pretty quickly. Maybe about half an AU.
If Earth moved closer to the sun, temperatures would increase significantly, leading to the melting of ice caps, changes in weather patterns, and potential harm to ecosystems and biodiversity. Life as we know it would be threatened due to the extreme heat and its impacts on the environment.
If the moon were closer to Earth, tides would be much stronger, which could lead to more extreme weather events. The increased gravitational pull may also affect the Earth's rotation, potentially causing changes in the length of days. Additionally, the moon's closer proximity could disrupt communication and navigation systems that rely on satellites orbiting the Earth.
If the earth got pulled in closer to the sun, or if the sun expands significantly, then the earth will get much warmer. That said, nothing like that is going to happen for a couple billion years yet.
An object have greater gravitational pull closer from earth. As we get farther from earth, the gravitational pull becomes weaker. That is why objects sufficiently away from the earth do not fall on it.
If only gravity were acting on Earth, it would continue revolving around the Sun in its elliptical orbit without any external forces to change its path. The force of gravity between the Earth and the Sun would keep Earth in its current orbit, so it would not be pulled closer to the Sun.
The earth would be attracted by the sun, and as it came closer the sun, the earth would melt. The earth would probably collide with the sun before or after it would melt.
The closer an object is to the sun, the more heat it receives. If Earth were too close to the sun it would be too hot to support life.
oceans would dry
If the moon were closer to Earth, high tides would be higher and occur more frequently due to increased gravitational pull. The closer proximity would enhance the moon's influence on Earth's tides, leading to more pronounced tidal variations.
Yes
Warmer
The Earth would be completely destroyed. However, everything and everyone would burn up before the Earth ever contacted the sun. Also, the sun would not "come hurling against the Earth" for any reason. The the Earth could possibly be pulled closer into orbit with the sun, at which point many animals and plant species would immediately go extinct, depending on how much closer Earth got to the sun (AUs)
if the earth came closer to earth all the waters would boil up and kill everyone, if the earth was further away, the water would freeze and all life would die
the sun moves closer to earth
It would get to hot. We would die.
If Earth moved closer to the sun, temperatures would increase significantly, leading to the melting of ice caps, changes in weather patterns, and potential harm to ecosystems and biodiversity. Life as we know it would be threatened due to the extreme heat and its impacts on the environment.
it's is impossible for earth to melt but if we were 20,000,000 miles closer the earth would not melt but the oceans would evaporate.
