Feb. 23, 2007: There is NO references to be found in SIMBAD or STScI star catalogs for the two stars: Y1 (one) Aurigae J Cassiopeiae.
If valid source material can be given, with RA and DEC - it would be most helpful. Otherwise I am thinking these are typos and we need to figure out exactly what stars these are SUPPOSE to be.

[edit] Contradiction Antares/Betelgeuse
Betelgeuse [...] if it were placed at the center of our solar system, its outer surface would possibly extend to the orbit of Jupiter.
Antares [...] with a diameter of approximately 1.33 × 10^9 km. I.e., if in place of our sun, it would slightly more than encompass the average orbit of Mars.
... and yet Antares is larger than Betelgeuse !
Somebody please check & correct.
Memo
- Betelgeuse's size is variable (between 500-800 Sol's), so the 650 size is an average. I think the Jupiter statement just refers to the max size of 800, so Antares is correctly listed above Betelgeuse, as this is fixed at 700. The Solar radius is 0.0046 AU, giving Antares a diameter of 3.25 AU and Betelgeuse 3 AU (r=650) or 3.72 (r=800).
- *The distance to Mars varries from 1.4 AU (min.) to 1.7 AU (max.)
- *The distance to Ceres varries from 2.5 AU (min.) to 3 AU (max.)
- *The distance to Jupiter varries from 4.95 AU (min.) to 5.46 AU (max.)
- So actually, neither the Mars- or the Jupiter statement is correct, both stars are between these two. Patrick1982 14:33, 14 March 2007 (UTC)
[edit] Relations between Solar radius and Orbital radius of planets
Solar radius(R) = 6.96 × 105 km.
Astronomical unit(AU) = 1.49597870691 × 108km = 214.9 Solar radius.
| Planet | (AU) | solar radius = 1.0 | example stars |
|---|---|---|---|
| Mercury | 0.31 - 0.47 | 66 - 100 | Rigel(70) |
| Venus | 0.73 - 0.73 | 156 - 158 | |
| Earth | 0.98 - 1.02 | 211 - 219 | Deneb(220) |
| Mars | 1.38 - 1.67 | 297 - 358 | |
| Alpha Herculis(460) Betelgeuse(650) Antares(700) | |||
| Jupiter | 4.95 - 5.46 | 1064 - 1173 | |
| VV Cephei (1600-1900) | |||
| Saturn | 9.02 - 10.05 | 1939 - 2161 | VY Canis Majoris (1800-2100) |
| Uranus | 18.29 - 20.10 | 3930 - 4320 | |
| Neptune | 29.81 - 30.33 | 6408 - 6519 |

[edit] Radius versus Diameter
Looking over the Solar diameter, I see the measurement is the same as the solar radii for Antares. Diameter is not radius. —The preceding unsigned comment was added by 71.241.214.116 (talk) 08:45, 3 April 2007 (UTC).
[edit] Distance from Earth
I think it might also be useful to add the the chart a listing of the distance from Earth in light-years for each star. 147.145.40.44 22:48, 30 April 2007 (UTC)
[edit] A1 in NGC 3603
This is an ultra massive star, likely the largest on this list, but I did not track down its diameter. [1] —Preceding unsigned comment added by 68.145.187.67 (talk) 17:06, 22 April 2008 (UTC)
