NASA Space probe, the first ever studied Pluto from a distance, withdrew from the Earth at seven billion miles, which allowed him for the first time also to see some stars on the reverse side.
the Reason for changing the positions of the stars for the probe is called the parallax effect or the change in apparent position of an object depending on the observer position. For example, it may be so: if you hold your finger at arm’s length from his face and turns to close the left and right eyes, it seems that the position of the finger changes.
according to NASA, in the new experiment the New Horizons probe watched the stars Proxima Centauri and Wolf 359 spaced, respectively, of 4.2 and 7.8 light years from Earth. And the machine is from her for more than seven billion kilometers.
According to a member of the research group New Horizons Todd Lauer, this experiment allows for the first time, so easy to observe stellar parallax.
the Us probe New Horizons was launched in 2006. In 2015 he first flew so close above the surface of Pluto and explored the asteroid Ultima Thule.
