Mars is now the closest to Earth than it has been in 15 years

Mars Close Approach: How to view the celestial event

Mars will be at its closest distance to Earth in 15 years tonight (Jul 31), wrapping up a memorable month for stargazers. Earth and Mars align in opposition about every two years (fun fact: this is why most NASA missions to the Red Planet are at least two years apart - to take advantage of the closer distance). Nope. In 2003, Mars was 34.6 million miles from Earth and the closest it had been in almost 60,000 years. Additionally, gravitational pull of the planets within our solar system constantly affects the shape of their orbits, moving Mars' orbit even closer to the Earth. Meanwhile the very bright planet Venus pops up in the very low western sky in the evening twilight, but sets shortly thereafter. The last instance of such occurrence was in 2003 than back in some 60,000 years, and right now it's now only slightly farther from Earth now than then. On July 31st, Mars will be 35.8 million miles from Earth, which is the closest it has been to Earth in 15 years.

Those who desire the terraforming of Mars suggest that a mixture of carbon dioxide and water vapor would from the greenhouse gases needed in order to heat the Red Planet. The minimum distance from the Earth to Mars is about 33.9 million miles. Since Mars is not as close to the Sun as Earth, scientists appraise a Carbon dioxide weight like Earth's aggregate environmental weight is expected to raise temperatures enough to take into consideration stable fluid water. This type of proximity won't occur again until 2287.

On the call, Jefferies & Co. analyst Brent Thill said that "many investors are having a hard time reconciling that deceleration". More likely, though, market buzzards are holding off because of how quickly some analysts are turning on the company.

If you're fortunate enough to spot the red planet through a telescope, you may be able to see the planet-wide dust storm that's been raging since June. Add a telescope and you can see a detailed view of the planet's surface and its polar caps. After rising, it stays up in the sky the entire night and starts setting in the west at a time when the sun rises in the east.

The closest approach on Tuesday will make Mars brightest since 2003. The late-summer skies are filled with celestial gems and this August also brings us three great planets! As Mars and the Sun appear opposite sides of the sky, we can call that Mars is in "opposition".
