Final chance to see stunning ‘comet of the century’ TONIGHT before it disappears for 80,000 years --[Reported by Umva mag]

Magnificent Comet A3 has been visible from the skies over the last few nights – and Tuesday is the last best shot of spotting it with your own eyes.

How to see Comet A3

Sky gazers need to look west to see Comet A3.

It’ll appear close to the horizon, so your best chance is away from buildings and with a wide view.

While the comet should be visible to the naked eye, it never hurts to be prepared for a dimmer display.

“Low on the horizon at sunset, it is best to wait a while for the sky to darken a bit before trying to see it,” advised Dr Greg Brown, astronomer at Royal Observatory Greenwich.

What's the difference between an asteroid, meteor and comet?

Here's what you need to know, according to Nasa...

Asteroid: An asteroid is a small rocky body that orbits the Sun. Most are found in the asteroid belt (between Mars and Jupiter) but they can be found anywhere (including in a path that can impact Earth)
Meteoroid: When two asteroids hit each other, the small chunks that break off are called meteoroids
Meteor: If a meteoroid enters the Earth’s atmosphere, it begins to vapourise and then becomes a meteor. On Earth, it’ll look like a streak of light in the sky, because the rock is burning up
Meteorite: If a meteoroid doesn’t vapourise completely and survives the trip through Earth’s atmosphere, it can land on the Earth. At that point, it becomes a meteorite
Comet: Like asteroids, a comet orbits the Sun. However rather than being made mostly of rock, a comet contains lots of ice and gas, which can result in amazing tails forming behind them (thanks to the ice and dust vaporizing)
