Unless I'm mistaken it should be divided by 3600 seconds, not 360 hours. This is close by; in fact Wolf 359 is the third closest star system to our own sun. Typically, the time scale for the spin down of a star at spectral class M6 is roughly 10 billion years, because fully convective stars like this lose their rotation more slowly than other stars. NASA's New Horizons spacecraft travels at nearly 60,000 km/h, the fastest a spacecraft has ever traveled in the Solar System. (ii) Calculate the distance in light-year from Earth to Wolf 359.

How did Laura the drone end up in the Delta Quadrant? For an Earth-like world to have liquid water . This prevents the buildup of helium in the stellar cores and prolongs the period of fusion, allowing low-mass red dwarfs to maintain the same spectral type and luminosity for trillions of years before they run out of fuel. Similarly, as Earth makes its way around the Sun, the stars shift their positions. Canis Minor ; 5.6 -9.9 ; 399 .
