The apex of the Sun's way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The general direction of the Sun's Galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 60 sky degrees to the direction of the Galactic Center. The Sun's orbit about the Milky Way is ...
Crux (/ k r ĘŚ k s /) is a constellation of the southern sky that is centred on four bright stars in a cross-shaped asterism commonly known as the Southern Cross. It lies on the southern end of the Milky Way's visible band. The name Crux is Latin for cross.
The solar apex is in the constellation of Hercules near the star Vega. [1]For more than 30 years before 1986 the speed of the Sun towards the solar apex was taken to be about 20 km/s [2] but all later studies give a smaller component in the vector toward galactic longitude 90°, reducing overall speed to about 13.4 km/s.

The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north.
“Even in our Milky Way galaxy we do not have such image.” Massive stars have shorter lives than less massive ones. For instance, the sun is already more than 4.5 billion years old and has ...

The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [26] It has an absolute magnitude of +4.83, estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs. [27] [28] It is more massive than 95% of the stars within 7 pc (23 ly). [29]
The Parker Solar Probe zoomed by the sun on Tuesday during a record-breaking flyby, coming within 3.8 million miles (6.1 million kilometers) of the solar surface during humanity’s closest ...
