minus-squaresilas@programming.devOPlinkfedilinkEnglisharrow-up2·edit-29 months agoI learned recently how the James Webb Space Telescope is not orbiting around Earth but literally orbiting around an empty point in space. I don’t think I even quite understand it, but it’s really cool
minus-square∟⊔⊤∦∣≶@lemmy.nzlinkfedilinkarrow-up2·9 months agoFor everyone who immediately thinks ‘it’s most likely orbiting a point within the earth,’ here’s a diagram to help:
minus-square0x4E4F@infosec.publinkfedilinkEnglisharrow-up0·9 months agoHave no idea how this works… there is no gravitational pull at the L2 point, it’s just an empty point in space 🤨.
minus-squareSneezycat@sopuli.xyzlinkfedilinkarrow-up2·9 months agoThere is gravitational pull, from both the Earth and the Sun. The JWST is orbiting the “earth-sun system” if you will. You can read more about Lagrange points here.
minus-squarePM_ME_FAT_ENBIES@lib.lgbtlinkfedilinkEnglisharrow-up1·9 months agoYeah but it’s not at the L2 point, it’s spinning in a circle around L2.
minus-square0x4E4F@infosec.publinkfedilinkEnglisharrow-up1·9 months agoYes, my point exactly. There is no mass at the L2 point, so how can it spin around it. Others explained it though, it makes sense now 👍. PS: What are enbies 🤨?
minus-squarekeepcarrot [she/her]@hexbear.netlinkfedilinkEnglisharrow-up0·9 months agoA Lagrange point or whatever?

Now I got that ZZ Top intro ear-worm…
