Information about the "planet parade" supposedly expected on June 3rd is not true. This was reported to TASS by astronomer Lyudmila Koshman from the Moscow Planetarium. Although Uranus, Venus, Neptune, and Saturn are indeed on the same side of the Sun, this is not considered a planet parade in the scientific sense.
The planets are too far apart from each other — about 90 degrees in the celestial sphere, whereas a real parade requires a much tighter convergence (20–30 degrees).
Uranus and Neptune will not be visible to the naked eye. Uranus itself is "hiding" in the sun's rays, making it inaccessible for observation.
Thus, no rare astronomical phenomenon should be expected on June 3rd. The situation described on the internet is a normal arrangement of planets, unrelated to a real parade.
