The galaxy MACS0647-JD (inset) appears very young and is only a fraction of the size of our own Milky Way. The galaxy is about 13.3 billion light-years from Earth, the farthest galaxy yet known, and formed 420 million years after the Big Bang.

Earth's lopsided orbit. Earthâs perihelion (point closest to Sun) = 91,400,000 miles from Sun. Earthâs aphelion (point farthest from Sun) = 94,500,000 miles from Sun. While that is a difference of over 3 million miles, relative to the entire distance, it isnât much.And, believe it or not, aphelionâwhen Earth is farthest from the Sunâoccurs in July, and perihelionâwhen we are closestâoccurs in January.any people believe that Earth is closer to the sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the sun in the winter. Although this idea makes sense, it is incorrect. It is true that Earthâs orbit is not a perfect circle.
