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.
In the top one-fourth of the planet, the pressure and temperature are so high that the hydrogen atoms are stripped of their outer electrons, forming a liquid metal. Like Jupiter, Saturn has a thick atmosphere composed of hydrogen and helium. The ratio of hydrogen to helium ratio decreases with depth. Methane and ammonia are also present. The atmosphere of Saturn envelops a thick layer of metallic hydrogen. The atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere are composed of crystals of methane. -=-=-=-=- Since gas giants do not actually have a surface, it is rather difficult to determine where their atmospheres end.
