Although his results were incorrect due to observational errors, they were based on correct geometric principles of parallax, and became the basis for estimates of the size of the solar system for almost 2000 years, until the transit of Venus was correctly observed in 1761 and 1769.

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax).

Parallax and distance measurements ... One of the few reliable methods astronomers may use to determine the distances to objects in space is called parallax. It is based on trigonometry, so let's start with that. ... There are times when it helps to use parallax to determine relative angles. Relative measurements,

Of course Svensmark's cosmic-ray/cloud theory could be wrong. It could be that the solar wind has some other not yet understood ways of affecting our climate, or it could be that some mechanism is amplifying TSI effects (in which case it is the IPCC's parameterization of TSI that is wrong).
