morabu Posted June 29, 2006 Report Share Posted June 29, 2006 YES......we are, but most of the other planets are gaseous, not alot of solid matter to them. and i need to read up, because i've never even heard of those other gigantic planets Quote Link to comment Share on other sites More sharing options...

Science Abuse Posted June 29, 2006 Report Share Posted June 29, 2006 Give it time, some day the sun will be larger then Pollux, then it will become as small as the earth. Quote Link to comment Share on other sites More sharing options...

Mowgli1647545497 Posted June 29, 2006 Author Report Share Posted June 29, 2006 Yes, everything on that page from the sun up are other stars, not planets. Also interesting to remember that our Moon is larger than the planet Pluto. Moon = 3476km across Pluto = 2274km across You could plug it into that picture halfway between Pluto and Mercury. And the largest moon in the solar system, Jupiter's Ganymede (followed by Titan by a hair), is larger than the planet Mercury. Quote Link to comment Share on other sites More sharing options...
Dr. Pomade Posted June 29, 2006 Report Share Posted June 29, 2006 Awesome find. The size of some of those stars is nearly incomprehensible. Quote Link to comment Share on other sites More sharing options...

The Pikey Posted June 29, 2006 Report Share Posted June 29, 2006 Here's another interesting thing to go along with the scale comparison. It scales the Earth's and Jupiter's orbit, compared to the size of Betelguese... http://www.seds.org/Maps/Stars_en/beteigeuze_add.html Scott peace Quote Link to comment Share on other sites More sharing options...
Orion Posted June 29, 2006 Report Share Posted June 29, 2006 roughly equivalent to being able to resolve a car's headlights at a distance of 6,000 miles. uh, wow. thats nutty. so, our star is pretty small. guess thats why superman is all strong and stuff.

black00ws6 Posted June 29, 2006 Report Share Posted June 29, 2006 I love science... about the huge star... ANTARES (Alpha Scorpii). A brilliant jewel set within the Milky Way, Antares guides us to one of the great constellations of the sky, the Zodiac's Scorpius (or Scorpio), the celestial scorpion, one of the few constellations that actually looks like what it represents. Antares, a class M (M1.5) red supergiant gleaming redly at the scorpion's heart, has a color similar to Mars. Since it is found within the Zodiac, which contains the apparent path of the Sun and planets, it is commonly mistaken for the red planet, a fact shown by its name, Antares, or "Ant-Ares," which means "like Mars," "Ares" being the Greek name for the god of war. This magnificent first magnitude (typically 0.96) star, shining opposite Betelgeuse, its counterpart in Orion, is ranked the 15th brightest in the sky. It is, however, a semi-regular variable that can change by several tenths of magnitude over a period of years. Its great distance of 600 light years reveals that it is truly luminous, to the eye over 10,000 times brighter than the Sun. Because it is cool, only about 3600 degrees Kelvin at its surface, it radiates a considerable amount of its light in the invisible infrared. When that is taken into account, the star becomes some 60,000 times brighter than the Sun. A low temperature coupled with high luminosity tells us that the star must be huge, luminosity and temperature giving a radius of about 3 Astronomical Units. It is so big that astronomers can easily detect and measure the size of its apparent disk, which gives an even bigger radius of 3.8 AU, three-fourths the size of the orbit of Jupiter The difference is caused by uncertainties in distance, temperature, and the actual location of the mass-losing surface, as the star is slowly evaporating under a fierce wind that has encased it in a gas cloud, or nebula, that shines by light scattered from the ultraluminous star within. Buried within the wind is a fifth magnitude (5.5) hot class B (B2.5) companion star (only 3 seconds of arc away) that hides within Antares' bright glare. The two are separated by roughly 550 AU and take perhaps 2500 years to orbit each other. The companion hollows out a small ionized region within the wind, and although blue-white, has the reputation of appearing green as a result of a contrast effect with its brilliant reddish mate. Antares, with a mass of 15 to 18 solar masses, probably does not have much time left to it. It is massive enough someday to develop an iron core and eventually to explode as a brilliant supernova. The event may be a million years off, an astronomical blink of an eye; or it may occur tonight, so keep a watch on one of the great stars of the nighttime sky. The companion, however, at around 7 to 8 solar masses, seems to be just below the supernova limit and will probably die as a massive white dwarf.

speedline Posted June 29, 2006 Report Share Posted June 29, 2006 YES......we are, but most of the other planets are gaseous, not alot of solid matter to them. and i need to read up, because i've never even heard of those other gigantic planets Those are stars. a planet that big would have too much gravity and would crush a human. if there was anything living on a planet that big it would be flat like. good find i love astronomy.

Its great distance of 600 light years so yeah, if it happens tonight, your going to be staring at the sky for quite some time before you see anything. *grin* i love astronomy.

Mensan Posted June 29, 2006 Report Share Posted June 29, 2006 so yeah, if it happens tonight, your going to be staring at the sky for quite some time before you see anything. What if it blew up just under 600 years ago? Quote Link to comment Share on other sites More sharing options...
Orion Posted June 29, 2006 Report Share Posted June 29, 2006 then it wouldnt have happened tonight. duh. Quote Link to comment Share on other sites More sharing options...

RedRocket1647545505 Posted June 29, 2006 Report Share Posted June 29, 2006 So, How do the scientists know that it hasn't blown up yet? Quote Link to comment Share on other sites More sharing options...
Mensan Posted June 29, 2006 Report Share Posted June 29, 2006 They don't. The further we see into space, the further we see into the past. http://i.somethingawful.com/forumsystem/emoticons/emot-synpa.gif Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 29, 2006 Report Share Posted June 29, 2006 Awesome find. The size of some of those stars is nearly incomprehensible. More incomprehensable is the smallness which many will achieve, collapsing in on themselves untill the are so dense that they dissapear from the observable universe, and light cannot escape them. "Infinite smallness". Quote Link to comment Share on other sites More sharing options...
