Discussion Overview

The discussion revolves around the distance from Earth to Pluto, exploring the implications of this distance through mathematical reasoning and historical context regarding space exploration. Participants reflect on the advancements in astronomy and space travel over the decades.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant calculates that traveling to Pluto at 400 mph would take approximately 770 years, illustrating the vast distance involved.
  • Another participant comments on the historical significance of discovering Pluto in the 1930s and contrasts it with contemporary attitudes towards funding for space exploration.
  • A different participant questions the relevance of lunar landings to the discussion of distances in the solar system, noting that these distances are minor compared to galactic scales.
  • One participant clarifies their earlier point about the media coverage of astronomical discoveries compared to celebrity events, emphasizing the perceived decline in public interest and funding for such advancements.
  • A later reply raises a hypothetical scenario regarding an unmanned flight to Pluto, asking about the targeting and success chances without the ability to make adjustments post-launch.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of historical achievements in space exploration to current funding and public interest in astronomy. There is no consensus on the implications of these distances or the priorities of space exploration today.

Contextual Notes

Participants reference historical advancements in space exploration and the current state of funding, but there are no settled definitions or assumptions regarding the significance of these points. The discussion includes speculative scenarios without definitive conclusions.

It's funny how simple math can help you visualize just how far away an object is.

Pluto is, at minimum, 2,700,000,000 (2.7 Billion) miles away from Earth.

Traveling at "airliner" speeds, say 400mph, a non-stop flight to Pluto would take:

6,750,000 hours en route, or...

281,250 days en route, or...

770 years en route!

I think it's pretty amazing, that in the 1930's, we were able to detect an object only 2/3 the size of our moon at this kind of distance.
 
Astronomy news on Phys.org
It is indeed! People who made those type of advances were respected world wide and celebrated for their achievements.
Worryingly nowadays is the current lack of funding and support for advancements. In 1930 it would take weeks to get to the far reaches of the world. by 1969 man had reached the moon and commercial flights were more viable. In the last 39 years, even with all the advances in technology, we still rely on the same principles and haven't even been back to the moon in 35 years!
Back then, advancement was worth the money, now its more will it make me a profit or not :(
 
Not sure what the lunar landing has to do with the enormanous distances seperating the various bodies of the solar system. Of course these distances are tiny compared to galactic distances.

I guess instead of putting Hubble into orbit we should have made another trip to the moon. :rolleyes:
 
Sorry should have made it more clear :P Was more the point they were able to spot Pluto in the 1930's, big news then but something similar would get less news time that some celebrity wedding, and would have to cost less too. Ofc we should have Hubble, but we should be doing both but people don't want to know now unless there's a profit in it.

If the flight to Pluto was unmanned and no adjustments were possible once the launch button was pressed, what would you be aiming at and what would be the chances of success ?
