Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light and radio, which radiates from stars and other celestial objects. It reveals information about composition, temperature, and motion.
The Solar Neighborhood contains stars within a few light-years of the Sun. These include Proxima Centauri, our closest stellar neighbor, and other systems that help us understand stellar evolution.
Diameter 12,742 km

Earth

The Blue Marble

Earth is the third planet from the Sun and the only astronomical object known to harbor life. With over 70% of its surface covered by ocean, it supports a diverse biosphere and complex climate systems protected by a magnetic field and atmosphere.

The Moon

Earth's Satellite

The Moon is Earth's only natural satellite. It is the fifth-largest satellite in the Solar System and the largest among planetary satellites relative to the size of the planet that it orbits. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day.
