Using the Solar System for comparison, the orbit of Mars is about 1.5 AU, Ceres in the asteroid belt 2.7 AU, Jupiter 5.5 AU —so, assuming Betelgeuse occupying the place of the Sun, its photosphere might extend beyond the Jovian orbit, not quite reaching Saturn at 9.5 AU.
The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris) Overview Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red ...
Terrestrial planets are substantially different from the giant planets, which might not have solid surfaces and are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. Terrestrial planets have a compact, rocky surfaces, and Venus, Earth, and Mars each also has an atmosphere. Their size, radius ...
Earth: 3rd Planet: Earth is the third planet from the Sun and the subject of historical misconception for centuries. [4] [5] Earth was never formally 'discovered' because it was never an unrecognized entity by humans. However, its shared identity with other bodies as a "planet" is a historically recent discovery.
Found in the constellation Orion, Betelgeuse is extremely bright, especially considering that it’s roughly 650 light-years from Earth (though, it does have a radius 1,000 times bigger than the Sun).
Its orbit revealed that it was a new planet, Uranus, the first ever discovered telescopically. [20] Giuseppe Piazzi discovered Ceres in 1801, a small world between Mars and Jupiter. It was considered another planet, but after subsequent discoveries of other small worlds in the same region, it and the others were eventually reclassified as ...
If Betelgeuse were too close to Earth, the eventual supernova could cause an extinction here on Earth. However, even at 530 light-years distance, our planet will still be safe from the eventual ...
The outer planets Jupiter, Saturn, Uranus and Neptune, compared to the inner planets Earth, Venus, Mars, and Mercury at the bottom right The four outer planets, called giant planets or Jovian planets, collectively make up 99% of the mass orbiting the Sun. [ h ] All four giant planets have multiple moons and a ring system, although only Saturn's ...
