What would happen if Mars crashed into Earth?
Computer models of a giant impact of a Mars-sized body with Earth indicate the impactor's core would likely penetrate Earth and fuse with its own core. This would leave the Moon with less metallic iron than other planetary bodies.
What would happen if the other planets disappeared?
Only the bigger planets' disappearance would cause changes over a period of time; namely, there would be a change in how some planets interact with each other. We think of our Solar System as a big family of celestial objects that interact with each other in various ways.
Is Mars a failed Earth?
In consequence, Mars became a failed Earth where only bacteria, fungi, and perhaps those living deep beneath the soil or within caves and crevices, are able to survive.
Could life still exist on Mars?
When conditions on the surface of Mars turned nasty, life may have become extinct there. But fossils may have been left behind. It's even possible that life could have survived on Mars below the surface, judging from some microbes on Earth that thrive miles underground.
What if Earth had rings?
At the equator, the rings would appear to divide the sun, casting a dramatic shadow over half the world. Likewise, the rings themselves would cast shadows on Earth.

What if Jupiter hit the Sun?
If Jupiter were mixed throughout the sun, the temperature of the sun would decrease slightly, and perhaps it would take a few hundred years for the sun's temperature to return to its previous level, and maybe we would get a few basis points less solar radiation, but it wouldn't go out. Highly active question.
How long has Mars been dead?
4 billion years ago However, tracing the Martian surface magnetic field indicated that Mars lost its magnetic field 4 billion years ago, leaving the atmosphere under severe attack by the solar wind.
How Mars lost its water?
Based on data gathered by NASA's Mars Atmosphere and Volatile Evolution (MAVEN), scientists suggest that dust storms rising from the Martian surface appear to have been slowly sucking away the planet's water over the course of millions of years, sweeping water molecules up on a wild journey into the atmosphere.
Which planet could we live on?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.

What if Earth had 2 moons?
If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.

Is Earth older than Mars?
“Mars is believed to be geologically older than Earth, yet (both) formed out of the same material very close to each other,” Matthew Clement, the paper's lead author and a graduate researcher in planetary science at the University of Oklahoma, told me.
Is Mars cold or hot?
cold Is Mars red hot? Mars may look hot, but don't let its color fool you — Mars is actually pretty cold! In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.
Does it rain on Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
Is Earth losing water?
Water flows endlessly between the ocean, atmosphere, and land. Earth's water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
How much longer can we live on Earth?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
Did NASA find another Earth?

What would happen if we had no gravity for 5 seconds?
Without gravity, the pressure of the Earth's inner core will cause the planet to expand. It's not like five seconds without gravity would cause the world to explode, but even a five-second expansion of the Earth's inner core would cause some major earthquakes, and trigger huge volcanic eruptions.

Is there gold on Mars?
In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts.
Was there life on Mars before?
To date, no proof of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.
Will we ever run out of oxygen?
Yes, sadly, the Earth will eventually run out of oxygen — but not for a long time. According to New Scientist, oxygen comprises about 21 percent of Earth's atmosphere. That robust concentration allows for large and complex organisms to live and thrive on our planet.
