APOD: Mars Approach (2018 Jun 01)

Post by APOD Robot » Fri Jun 01, 2018 4:07 am

Image Mars Approach

Explanation: Since the distance from Earth to Mars changes drastically as the planets orbit the Sun, Mars' appearance changes dramaticaly. Mars is bright now, and it's getting closer and brighter still as it orbits toward its 2018 opposition and closest approach to Earth in late July. This sequence of sharp telescopic images records the Red Planet's steady increase in apparent size for the months of January (top left) through April. During that time its distance from Earth went from 284 million kilometers in January to 129 million kilometers in April, and so its apparent size more than doubled. At closest approach Mars will be about 58 million kilometers distant, more than doubling in apparent size compared to the disk at the lower right. By then it will rival the brightness of Jupiter in planet Earth's night sky, but don't believe the claims of the inevitable internet hoax.

Damian Peach is a legend!

Also shouldn't the credit also include Chilescope?

Yeah, I can also remember "The Sands of Mars" by Arthur C. Clarke. And more appropriate to today's apod, "A Princess of Mars" by Edgar Rice Burroughs, in which Mars comes so close to Earth that a man called John Carter of Earth grows so fascinated and hypnotized by the orb of Mars that a certain wormhole opens up and Carter gets transported to Mars to become "John Carter, Warlord of Mars".

I hope to get much better pics now that I have 2 planetary cameras...I was over saturating images with my ten inch Meade...so I think this will be much better...my shots of Jupiter look awesome compared to the previous camera and work...

Bottom pic done with 10" Meade, and Deep Sky Imager 2

Top pic with Meade Lunar/Planetary Camera in Hi Def, with 6" Celestron Evolution, plus 2 power barlow...

ON TO MARS... and SATURN this summer....

How fast is your shutter speed with bright Jupiter?

What do you estimate for your resolution?
