196,938,790 Square Miles
Jupiter is 11.0 times the diameter of Earth.
Jupiter has 17 known moons and these numbers are always changing.
Its year is 11.86 (basically 12) Earth years long.
Its day is (incredibly) 9 hours 55 minutes 30 seconds.
The Sun is known in astronomical circles as Sol.
The Sun's mass is about 333,000 times Earth's mass.
An object at the Sun's surface would weigh 28 times as much as it does on Earth's surface!
A 200 pound man would weigh 5600 pounds on the Sun's surface!
The Sun is 1,391,000 kilometers (862,400 miles) in diameter.
Arcturus, or Alpha Boötis, is located about 36.7 light-years from Sol. It is the brightest star of Constellation Boötes, the Herdsman or Bear Driver, forming his left foot.
The diameter of Arcturus is 24.5 time that of our sun!
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
Its great distance of 600 light years reveals that it is truly luminous, to the eye over 10,000 times brighter than the Sun.
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
In a class called red supergiant, Antares is about 700 times the diameter of our own Sun and 15 times more massive.
Relative Sizes
Earth is 12,742 kilometers (7,900 miles) in diameter.
Jupiter is 142,802 kilometers (88,736 miles) in diameter
The Sun is 1,391,000 kilometers (862,400 miles) in diameter.
Artcturus is 34,079,500 kilometers (21,128,800 miles) in diameter.
Antares is 970,370,000 kilometers (603,680,000 miles) in diameter.
Antares is 15,007,943,291,139 Square Miles.
It would take 89,332,995,780 billion Rocky Boy's to cover Antares!
If Rocky Boy were a planet the diameter would be 7 miles!
"It's a small world!"
