The real estate term âunder contractâ means that a binding agreement exists between a buyer and a seller involving property. The buyer and the seller are in agreement with the terms in the contract. When a property is under contract, the seller may not enter into contract with any other buyer.
Much of the surface of Venus appears to be rather young. The global data set from radar imaging reveals a number of craters consistent with an average Venus surface age of 300 million to 500 million years. There are two continents, which are large regions several kilometers above the average elevation.
Venus itself rotates only once every 243 Earth days. Surface pressures on Venus are around 95,000 millibars. (By contrast, Earth has a sea-level pressure of around 1,000 millibars.) Mars, in contrast, has a thin atmosphere composed of about 95 percent carbon dioxide, with the remainder being mostly diatomic nitrogen. Traces of water vapour also occur. Mars has a mean surface air temperature estimated at 210 K (â63 Â°C, or â82 Â°F), and surface pressures hover near 6 millibars.
