Earth Closest to Sun: See the Difference!

On January 3, 2026, at 8:15 p.m. Moscow time, Earth will achieve perihelion, marking its closest approach to the Sun. At this point, the distance between our planet and the star will be minimal for the year, measuring 147,099,586.2593 km. Consequently, the Sun's diameter will appear largest, stretching to 32 minutes and 35 seconds of arc.

This celestial event, while visually striking, carries a significant warning from astronomers regarding direct solar observation. Attempting to view or photograph the Sun without specialized protective filters poses a serious risk of severe eye burns. Safety precautions are paramount for anyone interested in witnessing this phenomenon.

While January is not typically the prime season for solar viewing, telescopes can still reveal surface details. Regardless of the season or equipment used, the Moscow Planetarium stresses that all visual observations of the Sun necessitate the use of a dedicated solar filter to ensure viewer safety.
