Astronomy / Space A giant asteroid will graze the Earth on April 19

On April 19, an asteroid measuring one kilometer of diameter and considered by NASA to be "potentially dangerous" must pass close to the Earth. The asteroid, named "2014 JO25" and scrutinized for two years by several telescopes, should not however strike our planet. It will pass to 1.9 million kilometers from us. Approximately 5 times the Earth-Moon distance --- https://echo.jpl.nasa.gov/asteroids/2014JO25/2014JO25_planning.html --- (Impressive video of the orbit)

i am more interested in the comet 41P/Tuttle-Giacobini-Kresak
should be visible on the nightsky this month, without a telescope

yet, since they have said that on the radio, we only had either cloudy sky, fog or bright moon or all together.

If anyone is interested here is a spiel about it (the comet that is, not the asteroid), including "finder chart", from astronomy now:

I already know that it won't be visible in the southern hemisphere or if it is, it'll be at some ungodly hour, or not it will be so horribly overcast that I won't be able to see anything. Cos that's just how it rolls for me and astronomical events.

Nope, not a good idea, the IRS will descend on you...

Considering it should be somewhere between Polaris, Draco and the Big Dipper for a good while, I'd say it's pretty much out of view from your side. I tried to spot it in 10x50 binoculars from urban sky, but it's too dim and probably got drowned in light pollution, should be visible from suburban areas already in 4" and larger scopes. Unless it undergoes some flaring event or other kinds of surging (comet are mostly unpredictable), I doubt it'll be ever visible by naked eye alone.

There may be luck for southern observers indeed:

does anyone already know when and where the lost heatshield of the ISS will have its burning re-entry ?

I've found some photos from the ground of the piece trailing ahead of the station, but nothing about an exact date of re-entry. Given they said that after a few hours it was already starting to experience atmospheric drag, probably no one has a real clue about when it may happens exactly.

At first, the chances were calculated to be one in a Million; then one in ten thousand, then one in a hundred. Then began the first chapter.
