2 dni temu · The star, whose mass is roughly half that of the Sun, is currently 62 light-years from the Solar System. It was first noticed in 1999 using data from the Hipparcos satellite, and was estimated to pass less than 1.3 light-years (0.40 pc) from the Sun in 1.4 million years.
22 cze 2024 · Start with the speed of light: 299,792,458 meters per second. Calculate how many seconds are in a year: 365.25 days × 24 hours × 60 minutes × 60 seconds = 31,557,600 seconds. Multiply the speed of light by the number of seconds in a year. Here’s the formula:
5 dni temu · Answer. Verified. 343.5k + views. Hint: In astronomical physics, Light year is a unit used to measure distance. A light year is the distance which a light travels with the speed of light in vacuum which is c = 3 × 108msec−1 c = 3 × 10 8 m sec − 1 in one Year. This distance is called one light year. Complete step-by-step solution:

29 cze 2024 · The light takes 8.19 mins (8 mins and 19 secs) to travel from our Sun to the Earth. Light from the stars can take years or billions of years depending on their position in the universe.
2 dni temu · The Sun orbits the Galactic Center at a distance of 24,000 to 28,000 light-years. From Earth, it is 1 AU ( 1.496 × 108 km) or about 8 light-minutes away. Its diameter is about 1,391,400 km ( 864,600 mi ), 109 times that of Earth. Its mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System.
