Silver is also used in the production of electrical and electronic equipment, high-voltage contacts, solder, high-capacity silver-zinc and silver-cadmium batteries, and photovoltaic cells.

The Milky Way's closest neighbor is the Canis Major Dwarf.

The Moon is the only one in the Solar System that has a dipole magnetic field capable of creating a magnetosphere.

It contains approximately 60 globular clusters, 700 open clusters, and 400 planetary nebulae.

Light from the surface of the Sun to Earth travels about 8 minutes and 10 seconds.

In the case of finding life on other planets, NASA established an Office of Planetary Protection.

The Moon moves around the Earth in an ellipse with an eccentricity of 0.0554, therefore its distance from the Earth varies from 363.104 km to 405.696 km.

According to research carried out by the Hubble Large Telescope in 2014, it was calculated that the rotation of the Large Magellanic Cloud around its axis takes about 250 million years.

Throughout its history, Earth has had four different atmospheres.
