Explanation:
Can you spot the Solar System's four
rocky planets?
In the above
image taken on September 20,
all of them were visible in a single glance,
but some of them may be different than you think.
Pictured above, the brightest and highest object in the sky is the
planet Venus.
The object lowest in the sky is the
planet Mars,
while the object furthest to the left is the
planet Mercury.
The last remaining
point of light is . . . the bright
star Spica, which leaves the question --
where is the fourth rocky planet?
That would be
Earth, specifically part of
Australia,
visible across the entire bottom of the image.
