Venus and Saturn are on a visual crash course, and you can watch the planets make their close approach all this week.
The two planets are, of course, more than 800 million miles (nearly 130 million kilometers) apart on average, so there's no chance of them literally colliding. But their orbits will make them seem like they might from the vantage point of skywatchers here on Earth.
Starting Wednesday (Jan. 18), the planets will begin their close approach toward one another. About 45 minutes after sunset, look to the northwest sky, close to the horizon, and you'll spot the two planets. Venus will be substantially brighter than Saturn — it's the third brightest celestial body in the sky, after the sun and the moon.

The two planets will make their closest approach, also known as an appulse, on Sunday, (Jan. 22). At the same time, Venus and Saturn will also reach conjunction, which is when planets share the same right ascension (an angular distance used to locate celestial bodies in the night sky).
On Jan. 22, the planets will become visible from New York City at 5:18 pm EST (2218 GMT), according to skywatching site In-the-Sky.org about 14 degrees above the horizon in the southwest sky. (If you need help measuring that distance, it's about one and a half of your fists stacked on top of each other at arm's length.) The pair won't be visible for long, though — they'll sink below the horizon at 6:48 p.m. EST (2348 GMT).
But while they're visible on Sunday (Jan. 22), they'll appear to be extraordinarily close together, just a tiny one-third of a degree apart, according to NASA's Jet Propulsion Laboratory. That means they'll be close enough to see within the field of view of a pair of binoculars, and perhaps even some low-powered telescopes.
