Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That's all the rules!

Shooting him into the sun would be a waste of delta-v. Shoot him out of the solar system.

It might take more delta v but it would be worth it

Been a while since my Kerbal days when I read a bit about all this orbital mechanics crap and I remember that there was something counterintuitive about the delta-v required to hit the sun vs escape the solar system; I think compared to escaping, if you start from Earth you need almost 3x the delta-v to hit the sun, but I can't remember why. Something to do with the huge gravity well, because it got worse the closer you are to the sun

edit: lol I totally misread you, but also I found a video and duh yeah the reason was obvious: it's because we're moving around the sun at ~30km/s and to hit the sun you need to use that much delta-v to slow down to make your orbit tight enough to actually hit the sun instead of getting slingshotted / staying in orbit: https://youtu.be/LHvR1fRTW8g?si=1eIyeeqWR61wRu08. Escape velocity for the solar system is ~10km/s
