Answer:
If earth was 103 miles away from the sun, earth wouldn't be here, it would have burned up. But lets pretend that if earth didn't burn up, it wouldn't be able to support life because of these reasons. The temperature will be 10000 times hotter than it is now. The extreme heat will evaporate any water instantly, which means no water for plants to live in... There will also be no atmosphere because the sun will burn it up, because the sun will be in the atmosphere, so there will also be no oxygen.
