Nettet22. okt. 2024 · It is 50,000 light years away from the center of the Milky Way - it is so close to us, that some of the SagDEG's stars are actually in the outermost regions of the Milky Way! The representation of the SagDEG on the "Nearest Galaxies" image is just an artist's interpretation - the only real image we have shows the galaxy in the radio wavelength. The image on the preceding page was created to demonstrate that Alpha Centauri is not a star, but really a star system. Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are … Se mer Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.) When we talk about the distances to the stars, we no longer use the AU, or Astronomical Unit; commonly, the light … Se mer The methods astronomers use to measure distances to the stars are pieces of fundamental and active work in astronomy with important implications for how we understand the … Se mer The Voyager 1 spacecraft is on an interstellar mission. It is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. … Se mer Stars are not actually stationary objects! The Galaxy is rotating, and the stars are in orbit around its center. Not every star moves at the same rate - how fast they orbit can depend on where the star is located within the … Se mer
