Nothing at all. Mass and center of gravity is all that counts. If the Sun expanded so that the Earth was inside its envelope (ignoring heating and drag). the Earth would feel less pull and thus expand its orbit.
Well, last time I checked, the moon orbited the earth, not the sun. You might , however, argue, that it orbits the sun TOGETHER with earth, then it would take a year to make a full circle around it.
the earth would be destroyed
If the moon always orbited directly above the equator, the tides would be more extreme due to the alignment of the gravitational forces. This could lead to more frequent and higher tides, impacting coastal ecosystems and infrastructure. Additionally, the climate and weather patterns could be altered, potentially causing disruptions to ecosystems and human activities.
Earth would stay the same
oceans would dry
allways one half of earth only will get sunlight
Techincally speaking that would never happen. The moon would have to be VERY close to the Earth. The moon moves away from the earth 1.75 inches away from the earth each year, making the hours of the day longer. If the moon did orbit the earth in one day, this would happen around the time period the moon formed in space.
Galileo initially showed using phases of the planet venus that it orbited around the sun and not the earth, this supported a new model developed by Copernicus suggesting that the earth orbited the sun and not vice versa. It had always been assumed that the moon orbited the earth. Later with the invention of Newtonian physics, a more concise model of the solar system was developed using the laws of gravity explained that the much smaller earth would orbit around the much larger sun and that the smaller moon would orbit the larger earth.
No
If Earth orbited 96% closer than it currently does, its orbit would be, on average, 3.72 million miles (6 million km).
The centripetal force holding the earth on its axis will be so great that the gravity keeping the earth and the sun at the same distance will not be enough to keep the Earth close to the sun. We would essentially fly off into the nothingness of space and die.
The sun's gravity would pull the earth in to it and the earth would burn up
earth wouldn't have different seasons

Orbital patterns are determined by the mass of the body they are orbiting. So to answer your question a comets of a set mass would have a different orbit around the sun then the earth.
The earth is falling. It takes the earth an entire year to fall once around the sun.
