It is not part of the Leo constellation outline but is within the borders of the constellation. The flares emit X-rays and gamma rays. Determine the ratio However, only the rotational motion in the direction of the observer can be measured by this means, so the resulting data provides a lower limit on the star's rotation. [17] If these planets are confirmed, the setup of the system would be similar to but more extreme than that of nearby red dwarf Proxima Centauri, both having a close-in low-mass planet and a farther out higher-mass planet. Previous searches using ground-based, photographic astrometry . At a distance of approximately 7.9 light years from Earth, it has an apparent magnitude of 13.54 and can only be seen with a large telescope. Think about the distance from the Earth to Pluto. It comprises the closest set of stars, even if their light does take just over four years to reach us. Since it has less than 0.25 solar masses, it will never become a red giant.
