Explanation: On June 30 Venus and Jupiter were actually far apart, but both appeared close in western skies at dusk. Near the culmination of this year's gorgeous conjunction, the two bright evening planets are captured in the same telescopic field of view in this sharp digital stack of images taken after sunset from Poznań in west-central Poland. In fact, banded gas giant Jupiter was about 910 million kilometers from Poland. That's over 11 times farther than crescent Venus, only 78 million kilometers distant at the time. But since the diameter of giant planet Jupiter is over 11 times larger than Venus both planets show about the same angular size. Of course, 16th century Polish astronomer Nicolaus Copernicus would also have enjoyed the simultaneous telescopic view including Jupiter's four Galilean moons and a crescent Venus. Observations of Jupiter's moons and Venus' crescent phase were evidence for the Copernican or heliocentric model of the solar system.

Is this picture backwards?
I know Venus should show a crescent and Jupiter should be ‘full’
But I think the crescent is facing the wrong way
lol
I don’t know, but Joe’s is. ;’)
Naturally, there was a link to the AsteroidDay.org website. Their stated goal: "A global awareness movement to protect Earth from asteroid impacts".

Viewed from the ground, Jupiter was on top, and Venus was underneath him. Just sayin’.
OK, I’ll play...
Why the “(WARNING: Fruitcake Alert)” for ‘Asteroid Day’?
Ha! Good eye, I missed that.
LOL! That’s a good one!
Yep. Missed that one. Great pictures at the NASA website. I occasionally use them as my desktop background pic.
“OK, Ill play...
Why the (WARNING: Fruitcake Alert) for Asteroid Day?”
You don’t think it’s a little over the edge for this group to believe they can protect the earth from asteroid impacts? Heck, maybe even WAY over the edge.
I do.
I interpreted their purpose as helping to build public support for early warning spacecraft that could detect potentially hazardous asteroids that might not otherwise be easily detectable from Earth until too late, not that they were going to protect the Earth by themselves.
The last time I was able to see both planets was July 1. Jupiter was in the 2 o'clock position relative to Venus. Venus, of course, was the brighter of the two.
