Holmes Comet Coma Grows Bigger Than The Sun

coondoggie passed us a NetworkWorld article, as he does, noting that there is now an object in our solar system bigger than Sol. The Holmes comet has a huge coma, with a diameter scientists are now calculating to be larger than our own middle-sized star. "Scientists don't seem to have a guess as to how big it will ultimately become. The Holmes coma's diameter on Nov. 9 was 869,900 miles (1.4 million kilometers), based on measurements by Rachel Stevenson, Jan Kleyna and Pedro Lacerda of the University of Hawaii Institute for Astronomy. The sun's diameter, stated differently by various sources, is about 864,900 miles (1.392 million kilometers)."

Look, don't try to sound cool by calling the sun "Sol". It just sounds pompous.

A sun is a type of thing, Sol is the name of the sun that happens to be closes to us.

Oh no! No. This is as bad as all those people who have started pronouncing Uranus "your-an-us" rather than "your-a-nus" because they think it sounds more scientific that way. As if sounding "scientific" is a good thing as opposed to trying to make things as understandable as possible (and funny). A sun is not a type of thing. You can say it to mean that, put it with a lower case 's' and people will know what you mean, but we have a word that specifically means that with no ambiguity and the word is star. We have been calling the Sun "the Sun" for a long, long time. Other languages have their own words for the Sun and they are direct equivalents. They don't mean "stars" or even "stars with planets around them." Each word means, quite specifically The Sun. And the interesting thing is that one of those languages is Latin and its word for the Sun is "Sol." It is the direct equivalent word with the same meaning. Why you think translating something into another language is suddenly correct and using the native word incorrect I don't know. But I am suspicious that it is that same creeping desire on the part of some people to sound "scientific." The English speaking world has used the Sun for centuries quite happily without any ambiguity which has appeared out of nowhere in recent years.

The overwhelming majority of English speakers call it the Sun and don't mean stars and wouldn't think to mean stars. Almost nobody calls it Sol. Why introduce confusion?

The Sun. The Stars. Uranus [rude pronunciation].

Thank you.

Correct != pompous

Our sun's name is "Sol." It is correct to call it by its proper name.

I don't think it makes the speaker sound pompous at all. Appealing to one's own ethos to strengthen an argument makes someone sound pompous. Quoting the law to justify an opinion about morality makes someone sound pompous. Using the word "Virii" to mean "more than one computer virus" makes a speaker sound pompous, and is also incorrect.

But simply speaking in a technically precise manner, especially to a science-literate target audience on a techie/geeky website, is not in the least bit pompous.

I would go so far as to call it "expected."

Why not make a satellite hitch ride on one of these comets to the outer reaches of the solar system. Assuming they go there once every round, even hitching Halley's comet will get us further than Pioneer 1&2 have been in a shorter time, without wasting any precious fuel.

To hitch a ride on a passing comet, you can do one of two things:

1. Match velocities, and then land on it. -or-

2. Not match velocities, and then get smashed to bits by it.

Method 2 easily achieves your goal of travelling to the outer reaches of the solar system "without wasting any precious fuel". However, your satellite will no longer be functional, or even identifiable. But other than that, yeah, it's a great idea. :)
