The year 2017 was favored with dire predictions of destructive giant impacts, and the 15 days of darkness “forecast by NASA” was back again. Unusually, there was no sign of the “Mars will look as big as the full Moon” that's been a regular since 2003. But there's also a new non-event.

Here is a woodcut of a Leonid shower. It was as seen at Niagara Falls, New York. Mechanics' Magazine said this illustration was made by an editor named Pickering "who witnessed the scene." It was before 1923, but that's all the information I could find.

from the internet comes a rather audacious meme appropriating the NASA logo for a nonsensical tale of 15 days of darkness.

Think of the whole Solar System. That's the Sun, the planets, dwarf planets, moons, asteroids, Kuiper Belt and other outer Solar System bodies, and comets. The mass of the Sun is 99.8% of the mass of the whole system. It's big and bright! Our view of it is dimmed by clouds, blotted out for a few minutes during a solar eclipse, and not seen when our part of the Earth turns away from it. But what could possibly darken it for 15 days?

Yet a blogger assured us the Sun would look like this for 15 days. (Not an astronomy blogger!) It's an event that hasn't happened for a million years, she says. I'd say make that 4.5 billion years, the age of the Earth.
