That's because the orbit of the earth is nearly a perfect circle. If you draw it as an ellipse you are wrong. Yes, technically it is an ellipse, but it is not pronounced.
okay sadly and I mean SADLY there are so many religious type 'folk' who really believe that God changes the seasons just like he won't let us cause global warming and all species were made just as you see them. its pathetic really.
I know this is a bit late, I didn't see the reply earlier, but elliptical galaxies are typically much older than spiral galaxies, and have a disproportionately small amount of large stars in them, because large stars tend to burn out much faster than smaller stars. A large star, bigger than our sun, is necessary to create a supernova.By the way, Also majoring in astronomy/physics, so you are asking the wrong (or right, depending on your perspective) person for these questions. I took AST101 way back when before I started my core coursework.

There are non-scientific reasons?

The article mentions the ellipse orbit but then the diagram shows it as a circle

hey Mr. Proud of himself, if you learned so much in your astronomy class, tell me why the radius of a white dwarf decreases as you increase mass.
