Freddie Mercury: Asteroid named after late Queen star to mark 70th birthday
Freddie Mercury is honoured with an asteroid named after him to mark what would have been his 70th birthday.

An asteroid has been named after Freddie Mercury to mark what would have been the singer’s 70th birthday.

The Queen frontman has had his name attached to Asteroid 17473, which was discovered in 1991 - the year he died.

Queen guitarist Brian May told a gathering of 1,250 fans at Montreux Casino in Switzerland that the asteroid would now be known as Asteroid 17473 Freddiemercury.

May said the honour marked “Freddie’s outstanding influence in the world”.

He said: “And so - for its first appearance in public - Asteroid Freddiemercury - happy birthday Freddie!”

Issuing the certificate of designation, Joel Parker of the Southwest Research Institute said the asteroid was a celebration for a “charismatic singer”.

“Freddie Mercury sang, ‘I’m a shooting star leaping through the sky’ - and now that is even more true than ever before,” he said.

“But even if you can’t see Freddie Mercury leaping through the sky, you can be sure he’s there - 'floating around in ecstasy’, as he might sing - for millennia to come.”

Mercury Will Cross In Front Of The Sun In A Rare Event. Here's How To Watch
Stargazers, ready your (solar-filtered) telescopes: Mercury will pass directly across the sun on Monday for more than seven hours. And you can watch when it does — if you do it just right.

Stargazers, ready your (solar-filtered) telescopes: Mercury is about to pass directly across the sun for the first time in nearly a decade.

The innermost planet of our solar system will look like a small, dark circle cutting across the sun’s disc. In the U.S., the transit will begin shortly after 7:00 a.m. ET on Monday and continue for more than seven hours.

At least part of the transit, which only happens about 13 times every century, will be visible across the Americas, Europe, Africa and large portions of Asia.
