The asteroid – named 441987 (2010 NY65) – is marked as a concern because it's 230 metres in diameter and travelling just 7.9 lunar distances (that's about three million km) from us.
[...] If it were to strike, its weight could impact with a force 300 times greater than the Hiroshima bomb, scientists have predicted.
2010 NY65 was discovered on July 10, 2010 by the Wide-field Infrared Survey Explorer (WISE) spacecraft and is expected to make yearly close approaches to Earth until 2022.
It might sound far-fetched, but experts have warned that an asteroid crash that would wipe out humanity could be imminent.
Dr Alan Fitzsimmons, speaking ahead of asteroid week this month, said there is currently nothing we can do to stop a large space rock heading our way – and the impact would be catastrophic.
Well, an asteroid impact is certainly one way to solve all our problems.

I saw that but not how I can assess future hazard due to this object. Basically I need to take info from here [nasa.gov] and plug it into my own solar system sim (I do happen to have one, not that it is so great)?
But what about the 99.9999% of people who do not have a sim ready to go they can plug into?
Is it to go here [nasa.gov] and just look at the "Minimum Distance" column?

Wow, that's really, really close to exactly yearly. How come? Is there a visualization of the trajectory, somewhere?

I don't know anything beyond what's in TFS, but apparently it's a co-orbital [wikipedia.org] object, likely in a horseshoe orbit similar to 3753 Cruithne, the first discovered and best-known Earth co-orbital. These orbits are in resonance (astrospeak for a phase-locked loop) with Earth, so the instantaneous ratio floats over/under per orbit, but maintain a long-term ratio of exactly 1:1.

I only pasted the "close" ones and left out another from 2020:
