Step outside and see the asteroid Vesta using just binoculars

August 4, 2011 | By | 2 Comments

With the asteroid Vesta reaching opposition tomorrow, now is the time to step outside to look for it. It is easy to find with a decent finder chart and appears as a slightly red or orange star in binoculars. I suggest you observe Vesta over a couple of nights so you are sure […]

You may have seen the odd snippet of information in the Australian media about Comet Hartley being close to Earth. In spite of being relatively close on an astronomical scale at a mere 17.7 million kilometers , it isn’t particularly outstanding given its small size. It is also only visible low on the […]

As mentioned in my previous post, the asteroid 2010 TD54 will have a close encounter with the Earth tomorrow night at 8.50 pm AEST. Correction (13 October 2010): The flyby took place last night. Somehow I messed up my time change (i.e. the website that the flyby time was listed in used another […]

I have been following a very slow conversation on the Minor Planet Email list for the last couple of days about the recently discovered asteroid 2010 TD54. Essentially, the conversation boiled down to “…it’s getting brighter, but it’s not moving in the sky?”. The most logical reason for the fact that the asteroid […]

Where is asteroid Lutetia in the Solar System?

July 10, 2010 | By | Add a Comment

With the ESA’s Rosetta spacecraft passing the asteroid Lutetia tomorrow morning, I thought I would find out where in the Solar System it is. Well, to be honest I first tried making a finder chart in case it was easy to  see in a telescope (it isn’t particularly bright). That didn’t work because […]

Asteroid 2005 YU55 won’t impact Earth in next 100 years

April 30, 2010 | By | Add a Comment

The potentially Earth threatening asteroid 2005 YU55 was imaged by the Arecibo Radar (Radio) Telescope in Puerto Rico on April 19. Data collected during Arecibo’s observation of 2005 YU55 allowed the Near-Earth Object Program Office at NASA’s Jet Propulsion Laboratory to refine the space rock’s orbit, allowing scientists to rule out any possibility […]
