The Cost of a Wedding DJ. For professional wedding DJs, the average price is $150 per hour. This includes the services of a DJ as well as the equipment he will be using for the entire hour. This price also includes a planning consultation with the bride and groom prior to the event. Professional DJ services are usually priced $100 to $300 per hour. 2  However, do you know that you can save on the wedding DJ prices if you book for his services for the full event instead of hiring him in an hourly basis? 3  For instance, a wedding DJ will cost $300 for two hours if his service is at $150 per hour.
In addition to Earth, many of the other astronomical objects in the Solar System have atmospheres. These include all the gas giants, as well as Mars, Venus, and Pluto. Several moons and other bodies also have atmospheres, as do comets and the Sun. There is evidence that extrasolar planets can have an atmosphere.
The atmosphere of Mars is enriched considerably with the noble gas argon, in comparison to the atmosphere of the other planets within the Solar System. Unlike carbon dioxide, the argon content of the atmosphere does not condense, and hence the total amount of argon in the Mars atmosphere is constant.
