I read somewhere, Trump offered all the money in the world, even and
especially if not his, offered it to NASA if MAGA could deliver humans
to the Moon or Mars before the end of his first term. 20/20 eyes on 2020.

Fund a Einstein-Rosen Bridge?? No way! Build a mega Mega MEGA MAGA Wall!

Speaking of Roger Federer, someone created and shared a picture of
young Roger versus older Roger in a tennis match. They're shaking
hands one with the other. About a decade differential between the
hands. Not sure which one Roger won. So what if its photoshopped?!

This has got to be a troll,.....right ?

In “Futurama”, in the year 3000, the planet eventually has been renamed in
order to avoid jokes like that :)

</obSF>

<ObAstro>

As a rule of thumb, the semi-major axis of Jupiter’s orbit around Sol (the
Sun) is approximately 5 AU (astronomical unit).  Since the semi-major axis
of Terra (Earth) is approximately 1 AU, Jupiter is at least 4 AU or ca.
4 × 1.5 × 10⁸ ≈ (4 × 1 + 4 × 0.5) = 6 × 10⁸ (million) kilometers away from
there.  Uranus’ orbit lies *beyond* that of Jupiter, at ca. 20 AU from Sol,
i.e. at least 19 AU away from Terra.  [Note that those distances can vary
greatly because it is possible that Terra and another planet are on the
opposite sides of Sol.  The other planet is then said to be in (superior)
conjunction with Sol and Terra.]

It is a really nice exercise (which I happened to do after Christmas
together with my 10-year-old nephew, and he understood it) to calculate the
revolution period of Jupiter using Kepler’s Second Law of Planetary Motion

  T² ~ a³

(“the square of the revolution period of a planet is directly proportional
to the cube of the semi-major axis of its orbit”) [1] because it is very
easy to do if you calculate the revolution periods in years (Terra’s
revolution period!) and the semi-major axes in AUs:

  T_Jupiter²∕T_Terra² = a_Jupiter³∕a_Terra³

           T_Jupiter² = a_Jupiter³ × T_Terra²∕a_Terra³
                      = a_Jupiter³ × (1 year)²∕(1 AU)³

:)

            T_Jupiter = √(a_Jupiter³ × years²)
                      = √(5³) years
                      = √(5 × 5 × 5) years
                      = √(25 × 5) years
                      = √(25) × √5 years
                      ≈ 5 × 2 years
            T_Jupiter ≈ 10 years.

The textbook revolution period of Jupiter is ca. 11.86 years according to
Wolfram|Alpha.  √(25 × 5) = √125 ≈ 11.18.  Not bad, right?)

    [Taking the square root separately to arrive an at approximation just
     occurred to me now.  The two of us did the square root of 125 with a
     desktop calculator; I let him type and he loved it :)]

Likewise, when you know approximately the revolution period of another
planet of the Sol system, you can rather easily calculate how far away
from Terra it must be *at least*.

    [Homework assignment: 1. Calculate the revolution period of Uranus
     using Kepler’s laws.  2. Calculate the minimum distances to all the
     other planets given only their revolution periods.  3. Compare your
     results with the textbook values.]
