(a)
What would the period of Planet Nine’s orbit be?
(b)
Let’s imagine replacing the Sun with a black hole of the same mass as the sun. How does this change the
orbit of Planet Nine?
(c)
Now imagine that Planet Nine were 4 times more massive
than the Sun
. Using Newton’s version of Kepler’s
Law, calculate the new period of Planet Nine assuming the semi-major and semi-minor axes.

What would the period of Planet Nine’s orbit be?
(b)
Let’s imagine replacing the Sun with a black hole of the same mass as the sun. How does this change the
orbit of Planet Nine?
(c)
Now imagine that Planet Nine were 4 times more massive
than the Sun
. Using Newton’s version of Kepler’s
Law, calculate the new period of Planet Nine assuming the semi-major and semi-minor axes.

Astronomers speculate about Planet Nine, a massive body in the distant Solar System. Calculations are made about its orbit period, potential interactions with a black hole, and changes in period if it were more massive than the Sun. Utilizing Newton's version of Kepler's Law, astronomers delve into the dynamics of this hypothetical celestial body.

Group 1 Pluto and its moon, Charon, taken by New Horizons in 2015 There is some evidence from distant Solar System objects of a large massive body very far from the Sun, often referred to as Planet Nine. Astronomers predict that, if this body were to exist, Planet Nine would be on a moderately elliptical orbit; additionally, it would be 4 times more massive than the Earth. Astronomers also predict a semi-major axis of 600 AU and a semi-minor axis of 500 AU. (a) What would the period of Planet Nine s orbit be? (b) Let s imagine replacing the Sun with a black hole of the same mass as the sun. How does this change the orbit of Planet Nine? (c) Now imagine that Planet Nine were 4 times more massive than the Sun. Using Newton s version of Kepler s Law, calculate the new period of Planet Nine assuming the semi-major and semi-minor axes.
