Line of sight Venus and Jupiter

It would be nice if the wider population received an astronomical
report using line of sight perspective where the faster Venus moving
in an inner orbital circuit puts Jupiter to the right rather that the
geocentric 'Jupiter drops below Venus' in the usual right ascension

I think students are well able for these things but it will really
take off with 3D technologies.

The sight out there is nothing short of spectacular even without
putting the positions of the planets in context of the line of sight
and Venus moves outwards to take a position in front of the slower
moving and further Jupiter -

Right now I would say it is right up there with the resolution for
apparent retrogrades as from night to night the positions draw closer
until Venus turns outwards from our point of view in its orbital
circuit as all our circuits are bound to the Sun that is just out of
view !.

Truly,truly a sight to behold as an astronomer -

Surely there is some graphical whiz who can do something better than
the following animation to explain Venus putting Jupiter from left to
right of its orbital position and continuing round to the transit in
June as it overtakes the Earth in an inner orbital circuit. -

Sometimes it is dismaying knowing that any other person here could
have explained this in words or graphics in heliocentric mode but
chose not to or didn't really think about it before.

Well, I found this...

.... which is fun. You can advance either forward in time or backwards
in time by the day, month or year.

The greatest gift we can give students is to interpret the celestial
arena properly and use whatever tools we have at our disposal to make
them see what is going on with the Earth.Somehow with this gorgeous
show going on out there that the magnification guys can see my point
that sometimes you set aside the equipment and take in the spectacle
from an interpretative standpoint and that online orrery is excellent
to bridge any difficulty between observation and interpretation.In an
era where video games limit children to manual dexterity and the
limits of the program,astronomy has to actively compete for attention
notwithstanding the impossible demands such as 'big bang' and other
novelties like the analemma.A person trying to put the closing
distance between Venus and Jupiter in context of their actual
positions and motions in respect to the moving Earth cannot return to
ideas of a wandering Sun as the ballet of motions are orchestrated by
orbital motion alone,that of the Earth and the other planets on view.

A person moving between the online orrery and going directly outside
will experience the challenge provided by the ballet of planets
including the observation of Mars in apparent retrograde as the Earth
is just overtaking it,the best they could do was Kepler's
representation using the background stars whereas today's orrery's
make it so much easier .

Right now,Mars is at the bottom of one of those loops which can be
checked using a modern orrery so it is not a geocentric representation
as contemporaries believe but rather the combination of the Earth;s
and Mar's motion as intended by Kepler.

If people here love astronomy then they would not withdraw but stay
and work towards providing a picture that students and interested
adults enjoy and I was delighted to hear an elderly lady remark out of
the blue that she noticed two bright stars that stood out alone as
darkness set in.There is so much going on,and yes ,solar activity is
part of this,that there is room for any and all meaningful discussions
in this small portion of the limitless expanse of space and time that
we call home.

Well, it is true that Venus and Jupiter appear to be getting closer to
each other from our vantage point here on the surface of the Earth,
but if you go back to my reference URL and advance forward in time one
day at a time, you will see that in reality Venus is racing almost
directly away from Jupiter at a relatively high rate, while at the
same time racing almost directly towards Earth at our current position
in our orbit.

As always, it is a matter of perspective.
