It's a thought that may have crossed your mind at some point: what would be the practicalities of firing your enemies into the Sun?...

So the "straight" part is impossible, but otherwise you certainly can. All that matters is "enemies into the Sun".

[–] Fedizen@lemmy.world 7 points 2 months ago (4 children)

You could fire somebody straight at the sun but you'd need to launch them so fast they would be instantly vaporized.

[–] atro_city@fedia.io 2 points 2 months ago (1 children)

You're telling me we can slingshot a satellite around the moon and past Jupiter but hitting the sun is more difficult?

[–] Fedizen@lemmy.world 4 points 2 months ago

'Difficulty' here is apples and oranges. Energetically more expensive, but less complicated than slingshotting.

[–] TomMasz@lemmy.world 1 points 2 months ago

That would work and also be much faster.

Doesn't sound like a problem to me

[–] remon@ani.social 15 points 2 months ago (3 children)

Just fire them at earth-orbit speed in the opposite direction and they'll fall into the sun.

[–] teft@piefed.social 17 points 2 months ago (4 children)

That’s a fucload of delta-v. just shoot them out of the solar system. It’d be cheaper.

[–] shittydwarf@sh.itjust.works 8 points 2 months ago* (last edited 2 months ago)

Well we've got to get them in the sun somehow

[–] Delta_V@lemmy.world 6 points 2 months ago

If you don't mind waiting a few thousand years, you can cut the delta-v requirements in half by traveling to the edge of the solar system first and then burning retrograde at aphelion.

Or do like the Parker Solar Probe did and catch multiple gravity assists off Venus.

[–] grue@lemmy.world 3 points 2 months ago (1 children)

If you're really hell-bent on burning them up, I suppose you could aim them at some other star.

[–] moody@lemmings.world 2 points 2 months ago (1 children)

Or chuck them into an active volcano.

[–] grue@lemmy.world 1 points 2 months ago (1 children)

I mean, the idea was to try to fulfill both the "fire them into the Sun" and "minimize βˆ†V" requirements at the same time, but sure, that's an option too.

[–] moody@lemmings.world 1 points 2 months ago

Eh, just burn them in the volcano. The requirements are easier, and the Earth will eventually get burned up by the Sun anyway.

[–] fonix232@fedia.io 2 points 2 months ago (1 children)

Nah, just aim them for the sun and hope for the best.

They'll be dead due to lack of oxygen within a few days anyways, does it matter if their stinky corpses get burned up in the sun or not?

[–] ironhydroxide@sh.itjust.works 1 points 2 months ago (1 children)

Why bother to send them in a sealed vessel.

[–] fonix232@fedia.io 1 points 2 months ago

Why, the pretense of hope of course!

Then livestream their evil little faces as they realise they're about to run out of oxygen and there's nothing they can do about it 😈

Opposite direction? The earth is traveling at 67,000 mph. Opposite direction will require canceling out that energy first.

[–] remon@ani.social 5 points 2 months ago* (last edited 2 months ago)

Yes, that's exactly what we're trying to achieve. Once you cancel that out, the object will fall straight towards the sun.

[–] Valmond@lemmy.world 8 points 2 months ago (1 children)
[–] atro_city@fedia.io 2 points 2 months ago

You've gotta fire hard enough!

[–] fubarx@lemmy.world 8 points 2 months ago

Would be fine with towards the sun.

[–] mr_account@lemmy.world 5 points 2 months ago (2 children)

Idk why it's such a big deal for people to hit the sun in these hypothetical situations. Pretty sure the light radiating from the sun drops off exponentially as a function of distance, so anything getting even remotely "close" (i.e. thousands of kilometers) will still burn to a crisp

[–] lagoon8622@sh.itjust.works 11 points 2 months ago

It's about sending a message

[–] XeroxCool@lemmy.world 1 points 2 months ago

Correct. But even here at our orbit, the sun is still hot, damn hot. The sunny side of the moon peaks at 250F since there's no atmosphere to dampen the effect. Medium earth orbit is probably enough to get them roasted

[–] fox2263@lemmy.world 3 points 2 months ago (1 children)

Alright fine. How about near the sun

[–] Delta_V@lemmy.world 2 points 2 months ago (1 children)

Best I can do is a crash landing on Venus.

[–] fox2263@lemmy.world 2 points 2 months ago

Acceptable.

[–] phoenixz@lemmy.ca 3 points 2 months ago

We could if we could fire them on some rocket that can reach 30km/s speeds, they would just drift straight into the sun, over time

[–] eleijeep@piefed.social 3 points 2 months ago

Just get them to hitch a ride on Disaster Area's stunt ship.

[–] GhostPain@lemmy.world 1 points 2 months ago

Or just give me a few thousand and I'll make them disappear forever.

Way cheaper and I guarantee it will work.
