Question

Who is the scientist who discovered parallax?

Answer 1

See explanation

Explanation:

I am unable to name anyone for the discovery of parallax.

When you stand in the doorway of your train that is leaving the

platform, you keep turning your head for some time to wave

hands at your beloved one, who is responding from the platform

and giving you send off. The angle through which you turn is called

parallax.

If a star is observed like this, over a long period ( conveniently, half

a year ), from the Earth, the parallax is called stellar parallax.

According to https://en.wikipedia.org/wiki/Parallax, I find that

Friedrich Bessel was the first to make heliocentric measurement in

1838 ( I was born exactly 100 years later ) of stellar parallax for the

star named 61 Cygni
