Did Jupiter enter into the body of the constellation Virgo?

It's pretty easy to check.

You can download Stellarium, an easy to use, open-source planetarium software.

Launch it, search (Ctrl+F) for Jupiter, and press :

• Space to follow jupiter
• C for constellation lines
• V for constellation names
• R for constellation art
• G to disable the ground
• A to disable the atmosphere
• Ctrl+M for equatorial mount, so that the view doesn't rotate with the Earth anymore.
• You can either press F5 to input a time, press L multiple times for fast forward or press J multiple times for rewind.
• This way, you can follow Jupiter's path as seen from Earth in 2016 and 2017. You'll notice it is in Virgo, but only along her left arm. Jupiter doesn't come closer to her body, neither in 2016 nor in 2017.

If you look at the actual constellation of Virgo and not just the drawing superimposed over it, you will see that Jupiter was in the torso of Virgo.

Yes, Jupiter is now in the constellation of Virgo. Not only astronomers but everyone can see it with their own eyes (unless it's cloudy or you're in a big city where you cannot see a single star). Just find the Jupiter in the sky - see, it's in Virgo.

BTW, Mercury is in the Cancer now, Mars (with the Sun) in Gemini, Venus in Taurus and other planets in other constellations.

In case you cannot see the sky or do not know where which constellations is - use The Planets Today website to see in which constellation which planet is.
