“Predicted minimum distance is expected some 1.281 million years from now, possibly approaching as close as 0.0676 parsecs, 0.221 light years”—quote from wikipedia piece below

For the record, one light-year, the *distance* light travels in a year, at its ~steady rate of 186,000 miles per second, works out to about 5.9 Trillion miles. And so .221 light years is approximately 1.3 trillion miles. That’s 1,300 x 1 billion (miles).

“Gliese 710 or HIP 89825 is a orange star in the constellation Serpens Cauda whose main popular interest is its future significant close encounter with the Sun.

Predicted minimum distance is expected some 1.281 million years from now, possibly approaching as close as 0.0676 parsecs, 0.221 light years or about 13,300 AU[10]: being about 20 times closer than the current distance of Proxima Centauri.

It will then reach a similar brightness to the brightest planets, perhaps reaching an apparent visual magnitude of about -2.7 (brighter than Mars at opposition).

Maximum total proper motion will peak around one arc minute per year,[11][12] whose apparent motion will be readily noticeable over a human lifespan.

Gliese 710 currently is 63.8 light-years (19.6 parsecs) from Earth in the constellation Serpens and has a below naked-eye visual magnitude of 9.69.

Stellar classification of K7 Vk,[4] which means it is a small main sequence star mostly generating energy through the thermonuclear fusion of hydrogen at its core. (The suffix ‘k’ indicates that the spectrum shows absorption lines from interstellar matter.)

Stellar mass is about 60%[7] of the Sun’s mass with an estimated 67% of the Sun’s radius.[8]

It is suspected to be a variable star that may vary in magnitude from 9.65–9.69. As of 2017, no planets have been detected orbiting this star.
