It's Juice (Jupiter Icy Moons Explorer) and it's not yet anywhere near Jupiter. Its trajectory has a few slingshot loops around Venus and Earth, and it's just coming off the Venus encounter.

It's about 0.43 AU from the comet at its nearest, whereas Earth will be pretty much on the opposite side of the Sun, making observations difficult from here.

Edit: Earth, Mars and Jupiter are in roughly 120 degrees from each other as seen from the Sun, with the Earth-Sun-Jupiter angle closing up fast and the E-S-M angle growing slightly slower. In about two months the E-S-M angle will be 180.
