A cold, colorful afternoon in Vallentuna, Sweden. In the sky, a thin crescent moon with earthshine is visible, and to the left of the moon, the planet Saturn, and to the lower right, the planet Mercury.
Earthshine is an astronomical phenomenon in which sunlight is reflected from the Earth onto the dark night side of the moon, making the entire lunar disk faintly visible even when only a thin crescent is directly illuminated by the sun.
Mercury is the smallest planet in the solar system and the one closest to the sun. It is a rocky, so-called terrestrial planet with a surface filled with craters, which makes it very reminiscent of our moon.
Saturn is the second largest planet in the solar system and is best known for its spectacular and complex ring system. It is a gas giant that consists mainly of hydrogen and helium.
