Actually the ISS is orbiting at 7 km/sec. And the Titan is not in orbit now, it is always over the same part of the planet.

I just asked my self what are the effects of a Titan impacting on to a planet.

Well if the Titan crashs on the planet as some dust battles indicate, Caldari prime will face a extinction level event.
A leviathan class Titan is around the same size as the meteor that hit earth 65 mio. years ago that formed the chixculub crater in Mexico and removing the dinosaurs. The crater has a size of 160 km reaching 10 km in to the ground.
Of corse this meteor was not made of super robust alloys, covered in armor plates, had no shields an was not filled with, reactors, warpcores, jumpdrives, jump fuel and plenty of amo to destroy half a solar system.

The shockwave of a meteor impact will travel around the planet with supersonic speed leveling al the buildings in its path, creating serval earthquakes of high magnitude, eruptions of vulcanos and super tsunamis on the oceans. The heat of the shockwave would ignite serval large scale fires around the globe, burning most of the plants and city's.
the melted material of the impact would be thrown in to low orbit leading to serval high energy infrared radiation burst up on reentering the atmosphere, killing plankton insects bacteria and creating acid rain across the globe. It would change the composition of the atmosphere by reducing the oxygen level and adding carbon dioxide and other gases.
For the next 10 years or more, the atmosphere is so saturated with particles that only 10-20% of the sunlight will reach the ground. Leading to an ice age/ nuclear wither, or in case of Caldari prime reverting the planet to pre terraforming conditions.

In case of a Titan instead of a meteor, you can ad a mix of toxic and radioactive materials being spread al over the surface. With in an hour most of the population and animals would be dead, some will survive if they are lucky and in fortified underground facilities or in submarines diving.
Lets hope that if the titan goes down, it has a very brave captain with honor and love for nature (yea i know Caldari and honor, two things not going along very well) and some propulsion left to preform a crash landing instead of full impact. So it destroys only some citys instead of the whole surface.

The initial effects of the crash alone would certainly destroy tens of kilometers of cities and kill the people living there. Even if it isn't moving at high speeds, there is still a lot of mass. Beyond that, the dust and debris kicked up would have far reaching effects on an already marginal climate.

Also, if I remember correctly, warp drives can explode rather violently. I seem to remember something about an interceptor reactor overloading that caused huge problems during the retaking of Caldari Prime; now scale that up a hundred THOUSAND times.

It's not going to be a world ending event like an asteroid that size, but it will cause a lot of fuckupage destroying tens of kilometers of city and infrastructure and killing tens of thousands to millions of people depending on how populated an area it lands on and it will have a long term environmental impact.

You DO NOT want a capital ship hitting a populated planet ever.

It'll probably be on a scale comparable to Yakiya Tovil-Toba crashing his carrier into Gallente Prime early in the first war, with the difference being that the crew might be trying to mitigate the disaster as much as they can while they auger in.

pls delete this post, thought about who i was talking to, decided to just let it go...

titan jump drive+warp core=worse then meteor

you're new to eve, aren't you

Fortunately for us, Purdue University has an impact calculator that can give us a decent idea of what might happen. First, though, we need some numbers.

A Leviathan has a mass of 2,430,000,000 kg and a volume of 132,500,000 m3, which gives us an overall density of 18.34 kg/m3. Most of the titan is empty space, though its armor would resist a lot of the heat from reentry, so let's bump that to 20 kg/m3. It has a rough "diameter" of 3 km according to the model. Assuming it's propelled into the planet and doesn't just fall out of space, it could have a rough impact velocity of 25 km/s.

According to the site, this has the following effects:

A crater depth of 631 m and diameter of 2.97 km.
Magnitude 7.2 earthquake at the point of impact.
At 20 km from impact, 627 m/s wind velocity, major structural damage to buildings, and a catastrophic thermal blast.
At 40 km from impact, 245 m/s wind velocity, considerable structural damage, and a catastrophic thermal blast.
At 80 km from impact, 82.2 m/s wind velocity, slight structural damage, and enough thermal damage to severely burn people and set things on fire.

In short, utter devastation and incineration out to 40 km, with severe wind and thermal damage out past 80 km. It wouldn't be an extinction-level event, but it would obliterate the area it crashed into. By way of comparison, if it crashed in Trenton, NJ, the impact would destroy New York City, Philadelphia, and everything in between.

What of the citadel torpedoes that have a explosive radius of 2km and the doomsday weapon that can annihilate a State? I would imagine the power core of the titan would have to be powered by something immense and utterly volatile, as well as the 1 million or so stored megawatts in the capacitor that will disperse upon the ship's destruction. Let's not forget the fuel as well, which would add to the destruction. At the very least the amount of raw materials, gasses, and other unnatural materials that the titan consists of would destroy the planets ecosystem. This is assuming the titan pilot doesn't just decide to actually launch the doomsday weapon and fire off the citadel torpedos, because screw it he's going to die anyways.
