Its speed around the center of the Milky Way is about 220 km/s, so that it completes one revolution every 240 million years. This revolution is known as the Solar System's galactic year . [272] The solar apex , the direction of the Sun's path through interstellar space, is near the constellation Hercules in the direction of the current location ...
Local standard of rest. In astronomy, the local standard of rest or LSR is a reference frame which follows the mean motion of material in the Milky Way in the neighborhood of the Sun (stars in radius 100 pc from the Sun), [1] on average sharing the same velocity around the Milky Way as the Sun. [2] The path of this material is not precisely ...
Gaia Sky is an open-source astronomy visualisation desktop and VR program with versions for Windows, Linux and macOS.It is created and developed by Toni Sagristà Sellés in the framework of ESA's Gaia mission to create a billion-star multi-dimensional map of our Milky Way Galaxy, in the Gaia group of the Astronomisches Rechen-Institut (ZAH, Universität Heidelberg).
Milky Way with galactic plane, ecliptic and celestial equator. The galactic plane is the plane on which the majority of a disk-shaped galaxy 's mass lies.

Astronomers at Germany?s Ruhr-Universitt Bochum have managed to pack an impressive amount of it into a single photo.
English: Sun's Path Around the Milky Way. An illustration showing the path of the Sun, Earth and Moon around the Milky Way. The inclinations of the Ecliptic Plane and Celestial Equator are shown with respect to the Galactic North Pole and Galactic Plane. The inclination of the moon's orbit is shown relative to the Ecliptic Plane.
Galactic coordinate system. Artist's depiction of the Milky Way Galaxy showing the origin and orientation of galactic longitude. The galactic longitude ( l) runs from the Sun upwards in the image through the center of the galaxy. The galactic latitude ( b) is perpendicular to the image (i.e. coming out of the image) and also centered on the Sun.
