The distance of the planet from the star is about 300 million kilometers (or twice the distance of the Earth from the Sun). The planet's orbital period is 712 days - somewhat less than two Earth years - and the planet's mass is 5 to 10 times that of Jupiter.
The upper circle shows the location of the class G7 dwarf star HD 47186 in the constellation Canis Major, which has two planets, one quite small. The planets orbit their star with periods of 4.08 days and 3.7 years with (assuming the star to have a mass of 0.9 times that of the Sun) orbital sizes of 0.05 and 2.3 Astronomical Units. Lower limits to the masses are estimated at 0.0717 and 0.35 times that of Jupiter (23 and 111 times that of Earth. The system thus appears vaguely like our own Solar System, with an inner smaller planet 12 percent Mercury's distance from the Sun and a more Jovian one about where our asteroid belt would be.
A large planet recently found orbiting a distant star serves as a preview for the likely frying fate that awaits our own planet.
The star, called HD 47536, is more than 23 times the diameter of our Sun. It is the largest star ever found to harbor a planet. The discovery was announced Wednesday.
The planet is five to 10 times heavier than Jupiter and orbits the star more than twice as far as Earth is from the Sun, or at a distance of roughly 186 million miles (300 million kilometers). It goes around the star every 712 days.

So many possibilities.
The Zentraedi are one of those great villains of all time, the ultimate antagonist. They are a race of 40 foot giants, consumed with conquest and violence. Merciless warriors, they are relentless in combat and would rather die than acknowledge defeat. We can hate them because they are cold, cruel, and ruthless instruments of destruction. We can fear them because they are an enigma from another world possessing superior strength and numbers. We can loathe them for their cruelty, brutality and maniacal fervour to conquer...to destroy. We can sympathize for them because they are mere puppets, twisted and made ugly by an insane puppeteer. For they are victims of yet another race's mad design; artificially created, cloned, grown and indoctrinated into a short, bleak life of constant war and death. Toss in the mystery of the SDF-1 space fortress, protoculture, and the insane Robotech Masters, and there you have it. A truly compelling antagonist.
It would take over 7,000,000,000,000,000 (7 Quadrillion) earths to fill Canis Majoris.

Yep, the universe is just big beyond comprehension...
This is all, again, if we are a ridiculous tiny microbe on a marble sized planet around a 1 meter big star... Just how tiny we are, we cannot even represent it in our minds, it is totally beyond comprehension!
