[@0219-n1e]

Recently a paper published suggesting Pluto is a planet because it has enough gravity to shape a sphere and that is a correct definition for being a planet. what do you think Professor?

[@temdb3939]

If that’s the case, the moon is also a planet 🤨

m2-m1 = -2.50 log(B2/B1)
Sir plz make videos of how this formula come

[@asswan2256]

can delta m be a fractional number

[@praneethkapu8856]

i think it can be

[@MichelvanBiezen]

Yes, we make it whole numbers here to make it easier to understand, but in real life, they are often decimals

[@0219-n1e]

Amd how do you calculate 2.512 into 100times

[@MichelvanBiezen]

2.512^5 = 100

[@shridevishetty442]

And sir how that the value camed

[@MichelvanBiezen]

They picked a value such that the difference between 5 magnitudes would equal a difference in intensity of 100 to 1

[@shridevishetty442]

How that 2.512 came

[@shridevishetty442]

Please sir tell me please
