Then maybe you should ask them why they kept it secret for over a week
that a 23 mile wide asteroid came very close to Earth a few weeks ago
and flew lower than our satellites. They themselves say they only
knew about it for 15 hours before it passed us.
It was a small asteroid, only 23 ft across, and objects this size collide
with the earth all the time. 23 feet is nothing to worry about.

On November 6, 2009, The Catalina Sky Survey noticed something in the sky —
an asteroid, seemingly on a collision course with Earth. The object would
miss our planet by a mere 8,700 miles.
Terrifying? Hardly. Although the asteriod, identified as 2009 VA, would be
the third-closest known (non-impacting) asteroid ever, it was also just 23
feet across. Similar sized objects pass this close to Earth about twice a
year and impact the planet about once every five years.
The Nasa NEO programme aims to detect and track at least 90 per cent of the
1,000 asteroids and comets that approach Earth and are larger than 0.6miles
in diameter, by 2020.
They monitored a 100ft asteroid that whizzed 45,000 miles above the Earth's
surface on March 2 this year. A similar sized object slammed into Tunguska,
Siberia in 1908. The impact created a blast so powerful it levelled 1,200
square miles of forest.
