Nice app but it could be better by listing asteroid perigees to earth by date from closest to farthest express in Lunar Distances (LD).

Would be a great app if one can read it. The color cant be changed and the font is hard to read. I am going to uninstall it.

It's a great application, though more specifics about the asteroid would be useful.

why this app doesn't have a search bar to search for a specific astroid for example Apophis I'm very disappointed .

Just installed it again in hopes of improvement. Would love to see neo's years coming. Like when apophis will arrive.

It's amazing to see Neo object sitting in home to keep safe of our planet and we can know about the space rock's..

This is less alarmist and more scientific than some of the other asteroid trackers. The design, which gets better all the time, is clean, nice to look at, and easy to navigate. Tells you pretty much everything you need to know about nearby space rocks. I really like the addition of lunar distances with this update! For me the moon's orbit is much more tangible than kilometers or the color-based distance scale.

i love this app.hopes it alerts if an asteroid is coming close to earth.never try it out but I will get my information here.

Used to be good but not anymore. Very slow and bugy. Will delete it from my samsung.

Chr. D. Apr 11, 2015     

Excellent app with loads of information. Would be good if it could give notifications of those that come close to Earth eg less than 3 lunar distances. Thanks

A solid app for what it does and fairly reliable. My old app for this stopped working so I switched to this one.

As of 2016-12-12 this app still lists 2016 WJ1 as Torino Scale 1 it was removed on 2016-12-02 at 21:33(UTC). Many observers from around the world spend time (and money) to get the observations to removed it.

Bri. A. Aug 30, 2014     

It stopped updating a few days ago. Please fix. Like the app a lot!

Dev. B. Jan 25, 2015     

Longer listing would be nice, and the ability to sort by distance, size, etc.

Dav. S. Oct 19, 2016     

Excellent 5 stars if push notifications of a close one coming or choice of notifications

Dre. W. Nov 18, 2015     

Impressed by this app much better than the other apps so far

Arj. v. d. P. May 10, 2014     

Impressive. I like the browser links to each neo's data.

San. K. May 30, 2014     

But doesnot show the path of astroid. Add this.
