Trivia

Hard to believe

  • It would float. It is less dense than water. Drop it in a big enough ocean and the whole world would bob on the surface.

What it actually is

  • What it is made of. Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.

Find it in the sky

  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around June — that's when to go looking.

By the numbers

  • Size. About 13.9× the width of Earth.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Mass. Roughly 250× Earth's mass — about 0.8 Jupiters.
  • Volume. About 2686 Earths could fit inside it.
