Aww…look: a baby planet! This is the youngest known exoplanet—a mere 5 to 10 million years old. It orbits its star every 5 days—a ridiculously short year which puts even Mercury’s 88 day orbit to shame (although, to be fair, the planet is 10 times closer to its star than Mercury is to the sun). The newly discovered world is approximately 500 light years from Earth. Researchers discovered the world with the Kepler space telescope (which continues to disgorge a treasure trove of data, even after its primary mission has ended because of mechanical failure).
The planet is thought to be about the size of Neptune. Since its star, K2-33, is only 10 million years old, the planet is assumed to be younger than that…though who knows. The strange nature of this system may cause scientists to rethink and refine their models of planetary formation. It isn’t the sort of thing they expected (though these super-hot giant planets right next to their stars seem to be more common than anyone would have guessed).
The Perissodactyls (horses, rhinos, and tapirs) were the planet’s dominant grazers for many millions of years–from the beginning of the Eocene to the end of the Miocene–but, in the most recent geological period they have been greatly outnumbered and outcompeted by the multitudinous artiodactyls (pigs, cows, deer, goats, antelopes, giraffes, and so on). The vast distance separating the Earth’s remaining tapirs illustrates how much their range has shrunk. Three species live in very different parts of South America and one live on the other side of the world in Malaysia and Indonesia. The tapir species look different as adults but their incredible similarity as calves indicated their fundamental closeness. Such a study is also a study of insufferable cuteness since juvenile tapirs, with their waving proboscises and dappled coats are very endearing. Although the tapirs are vanishing from the wild there are more of each of the 4 species in zoos every year. Here are some more of the new ones for your viewing pleasure!
Hooray for little tapirs!
