I actually did mean 'heretical', but the comparison is honestly funny :-)
P.S. If we lived on a planet somewhere in the Orion Nebula, would we even know that some ‘star’ on the outer edge of a nearby galaxy(Milky Way) even had planets ? What would make that one star stand out amongst the millions of other stars , such that we would even pay attention to it ?
There could be billions of civiliations on billions of planets, and none of them would probably ever know any others existed.

The nearest star system is only about 4.3 light-years away. Meaning that at the speed of light (186,000 miles/second) it would take 4.3 years to get there.
One light-year, the distance light travels in one year, works out to about 5.9 *trillion* (with a T)(1,000 x a billion) miles.
And so: 5.9 x 4.3 = 25.4 trillion miles (Alpha Centauri)
Alpha Centauri was the place the Lost In Space crew meant to go.
Sorry. Meant that as a reply to al baby’s post 66, since he was the one I quoted.
From wiki...
Alpha Centauri, also known as Rigil Kent[12] or Toliman,[14] is the closest star system to the Solar System at 4.37 light-years.[5]
It consists of three stars, the pair Alpha Centauri A and Alpha Centauri B and a small and faint red dwarf, Alpha Centauri C, better known as Proxima Centauri, that is probably (but not certainly) gravitationally bound to the other two.[15]
To the unaided eye, the two main components appear as a single object of an apparent visual magnitude of -0.27, forming the brightest star in the southern constellation Centaurus and the third-brightest star in the night sky, only outshone by Sirius and Canopus.
Alpha Centauri A has 110% of the mass and 151.9% the luminosity of the Sun, and Alpha Centauri B is smaller and cooler, at 90.7% of the Sun’s mass and 44.5% of its luminosity.[16]
During the pair’s 79.91-year orbit about a common center,[17] the distance between them varies from about that between Pluto and the Sun to that between Saturn and the Sun.
Proxima is at the slightly smaller distance of 1.29 parsecs or 4.24 light years from the Sun, making it the closest star to the Sun, even though it is not visible to the naked eye.
The separation of Proxima from Alpha Centauri AB is about 0.06 parsecs, 0.2 light years or 15,000 astronomical units (AU),[18] equivalent to 500 times the size of Neptune’s orbit.

Thanks for that now I understand also lost in space had me rivited back in the day
