The planet Jupiter will come to opposition (be directly opposite the Sun) at 8.34 am GMT on Saturday 10 January 2026. This means that it will be at its closest to the Earth this year, about 4.23 AU (4.23 times the average distance between the Earth and the Sun, or about 632 800 000 km), and completely illuminated by the Sun. While it is not obvious to the naked eye observer, the planets have phases just like those of the Moon; being further from the Sun than the Earth, Jupiter is 'full' when directly opposite the Sun.

While the relative positions of the planets have no direct influence on life on Earth, the opposition of Jupiter does present the best opportunity for observations of the planet by Earth-based observers. On Saturday 10 January, Jupiter will appear as a bright object in the constellation of Gemini. Seen through a moderate sized telescope both the planet and its larger moons should be visible, although the Moon will be quite bright, being just before its third quarter, which may hamper viewing somewhat.
