Sir Isaac Newton proposed the elliptical orbit of the planets but he also contributed to the other options. So one can say all of the above in terms of his contributions.

The Goddard Space Flight Center  commemorates the contributions of Robert Goddard to rocketry.

The Greeks assigned what magnitude to the brightest stars seen in the night sky as 1.

The apparent magnitude of Vega is 0 is a true statement.

What are the stars about?

The magnitude scale that was made with the Greeks, shows the brightest stars in the sky as it is tagged "first magnitude" and the faintest stars is tagged "sixth magnitude."

Note that the apparent magnitude of zero is one that tells the brightness of the star known to be Vega.

So therefore, the answers are:

  1. All options
  2. b
  3. 1
  4. True
