The diameter of the Sun is about 1,390,000 km, and its nearest neighboring star, Proxima Centauri, is 4.22 light years (3.99 x 1013 km) away. Therefore, the ratio of distance to diameter is 28,700,000 : 1, so if the Sun were one centimeter in diameter, Proxima Centauri would be 287 km away.

A solar observatory is an observatory that specializes in monitoring the Sun. As such, they usually have one or more solar telescopes.

The Einstein Tower was a solar observatory in the Albert Einstein Science Park in Potsdam, Germany.

Solar observatories study phenomena associated with the Sun. The Sun, being the closest star to earth, allows a unique chance to study stellar physics with high-resolution. It was, until the 1990s, the only star whose surface had been resolved. General topics that interest a solar astronomer are its 11-year periodicity (i.e., the Solar Cycle), sunspots, magnetic field activity (see solar dynamo), solar flares, coronal mass ejections, differential rotation, and plasma physics.

The 160-minute solar cycle was an apparent periodic oscillation in the solar surface which was observed in a number of early sets of data collected for helioseismology.

The presence of a 160 minute cycle in the Sun is not substantiated by contemporary solar observations, and the historical signal is considered by main-stream scientists to occur as the redistribution of power from the diurnal cycle as a result of the observation window and atmospheric extinction.
